Australia: What is the total number of confirmed deaths?

Three points on confirmed death figures to keep in mind:

All three points are true for all currently available international data sources on COVID-19 deaths.

  • the actual total death toll from COVID-19 is likely to be higher than the number of confirmed deaths – this is due to limited testing and problems in the attribution of the cause of death; the difference between reported confirmed deaths and total deaths varies by country
  • how COVID-19 deaths are recorded may differ between countries (e.g. some countries may only count hospital deaths, whilst others have started to include deaths in homes)
  • the reported death figures on a given date does not necessarily show the number of new deaths on that day: this is due to delays in reporting.

→ We provide more detail on these three points in the section ‘Deaths from COVID-19: background‘.

Two tips on how you can interact with this chart

  • Add any other country to this chart: click on the Add country button to compare with any other country.
  • View this data on a world map: switch to a global map of confirmed deaths using the ‘MAP’ tab at the bottom of the chart.

Australia: Total confirmed deaths: how rapidly have they increased compared to other countries?

Charts which simply show the change in confirmed deaths over time are not very useful to answer the question of how the speed of the outbreak compares between different countries. This is because the outbreak of COVID-19 did not begin at the same time in all countries.

This chart here is designed to allow such comparisons.

The trajectory for each country begins on the day when that country had 5 confirmed deaths.

This allows you to compare how rapidly the number of confirmed deaths increased after the outbreak reached a similar stage in each country.

The grey lines in the background help you to see how rapidly the number of confirmed deaths is increasing

These lines show the trajectories for doubling times of 1, 2, 3, 5, and 10 days. If the slope that a country is on is steeper than a particular grey line, then the doubling time of confirmed cases in that country is faster than that. For example, there are several countries for which the slope was steeper than the ‘…every 2 days’ line – this means their death count doubled faster than every two days

How you can interact with this chart

  • Clicking on any country in the chart highlights that country. If you click on several countries you can create a view in which you can compare several countries.
  • Any country you might not see immediately you can find via the ‘Select Countries’ in the bottom left. Just type the name in the search box there.
  • To focus on the countries you highlighted click on ‘Zoom to selection’.

Australia: What is the daily number of confirmed deaths?

The previous charts looked at the increase of total confirmed deaths – this chart shows the number of confirmed deaths per day.

Why is it helpful to also look at the three-day rolling average of daily confirmed deaths?

For all global data sources on the pandemic, daily data does not necessarily refer to deaths on that day – but to the deaths reported on that day.

Since reporting can vary very significantly from day to day – irrespectively of any actual variation of deaths – it is helpful to view the three-day rolling average of the daily figures. Above the chart you find the link to the rolling three-day average view.

→ We provide more detail in the section ‘Reported new cases on a particular day do not necessarily represent new cases on that day‘.

Another tip on how you can interact with this chart

By pulling the ends of the blue time slider you can focus the chart on a particular period. If you bring them together to one point in time then the line chart becomes a bar chart – this of course only makes sense if you compare countries (that is what the Add country button is for).

Australia: Daily confirmed deaths: are we bending the curve?

This trajectory chart shows whether countries make progress on bringing down the curve of new deaths.

To allow comparisons between countries the trajectory for each country begins on the day when that country first reported 5 daily deaths.

By default this chart is shown on a logarithmic vertical axis. We explain why in the next section. If you are not familiar with logarithmic axes we recommend you also look at this chart on a linear axis. The visual representation on these different axes can look very different.

This chart is shown on log axis, but you can switch to a linear axis

  • The default view on a logarithmic y-axis is helpful to compare the growth rates between countries: on a logarithmic axis the steepness of the line corresponds to the growth rate. [Here is an explanation for how to read logarithmic axes.]
  • But in this chart – as in many of our charts – you can switch to a linear axis – just click on ‘LOG’.

Australia: Daily confirmed deaths: when did countries bend the curve?

This chart shows the number of daily confirmed deaths (on the y-axis) plotted against the total number of confirmed deaths (on the x-axis).

Plotting the data in this way allows us to see when different countries bent the curve.

How you can interact with this chart

Clicking on any country in the chart highlights that country. If you click on several countries you can create a view in which you can compare several countries.

Any country you might not see immediately you can find via the ‘Select Countries’ in the bottom left. Just type the name in the search box there.

Australia: Weekly deaths: where are confirmed deaths increasing or falling?

Why is it useful to look at weekly changes in deaths?

For all global data sources on the pandemic, daily data does not necessarily refer to deaths on that day – but to the deaths reported on that day.

Since reporting can vary very significantly from day to day – irrespectively of any actual variation of deaths – it is helpful to look at changes from week to week. This provides a slightly clearer picture of where the pandemic is accelerating, slowing, or in fact reducing.

The two maps shown here provide figures on weekly deaths: one shows the number of deaths in the previous seven days (the weekly total); the other shows the weekly growth rate.

Three tips on how to interact with these maps

  • By clicking on any country on the map you see the change over time in this country.
  • By moving the time slider (below the map) you can see how the global situation has changed over time.
  • You can focus on a particular world region using the dropdown menu to the top-right of the map.

Australia: Global comparison: where are confirmed deaths increasing most rapidly?

Simply looking at the total or daily number of confirmed deaths does not allow us to understand or compare the speed at which the toll is rising.

The table here shows how long it has taken for the number of deaths to double in each country for which we have data. The table also shows how the total number of confirmed deaths, and the number of daily new confirmed deaths, and how those numbers have changed over the last 14 days.

A tip on how to interact with this table

You can sort the table by any of the columns by clicking on the column header.

Australia: World maps: Confirmed deaths relative to the size of the population

Why adjust for the size of the population?

It can be insightful to know not just how many have died compared to how many people actually live in that country.

For instance, if 1,000 people died in Iceland, out of a population of about 340,000, that would have a far bigger impact than the same number dying in the USA, with its population of 331 million.1 The death count in more populous countries tends to be higher – here you can see this correlation.

This is why the two maps below show the deaths per million people of each country’s population.

Three tips on how to interact with these maps

  • By clicking on any country on the map you see the change over time in this country.
  • By moving the time slider (below the map) you can see how the global situation has changed over time.
  • You can focus on a particular world region using the dropdown menu to the top-right of the map.

Why is data on testing important?

No country knows the total number of people infected with COVID-19. All we know is the infection status of those who have been tested. All those who have a lab-confirmed infection are counted as confirmed cases.

This means that the counts of confirmed cases depend on how much a country actually tests. Without testing there is no data.

Testing is our window onto the pandemic and how it is spreading. Without data on who is infected by the virus we have no way of understanding the pandemic. Without this data we can not know which countries are doing well, and which are just underreporting cases and deaths.

To interpret any data on confirmed cases we need to know how much testing for COVID-19 the country actually does.

The Our World in Data COVID-19 Testing dataset

Because testing is so very crucial to understanding the spread of the pandemic and responding appropriately we have focused our efforts on building a global dataset on COVID-19 testing. 

  • The testing dataset is updated around twice a week. The latest version is always available in the section below.
  • And as with all our work, it is freely accessible for everyone. The data can be downloaded here on GitHub.

Australia: How many tests are performed each day?

This chart shows the number of daily tests per thousand people. Because the number of tests is often volatile from day to day, we show the figures as a seven-day rolling average.

What is counted as a test?

The number of tests does not refer to the same in each country – one difference is that some countries report the number of people tested, while others report the number of tests (which can be higher if the same person is tested more than once). And other countries report their testing data in a way that leaves it unclear what the test count refers to exactly.

We indicate the differences in the chart and explain them in detail in our accompanying source descriptions.

How to interact with this chart

  • By clicking on  Add country  you can show and compare the data for any country in the world you are interested in.
  • If you move both ends of the time-slider to a single point you will see a bar chart for this point in time.
  • You can switch to the ‘MAP’ tab.

In all our charts you can download the data

We want everyone to built on top of our work and therefore we always make all our data always available for download. Click on the ‘Data’-tab below the chart and you can download the shown data for all countries in a simple to use csv file.

Australia: How many tests are performed relative to the scale of the outbreak?

In order to properly monitor the spread of the virus, countries with more widespread outbreaks need to do more testing.

So if we want to understand how sufficient a country’s level of testing may be, we need to bring together the data on testing with the data on confirmed cases.

This is what we show in the chart here.

On the vertical axis is the daily number of tests per million people. On the horizontal axis is the daily number of new confirmed cases per million people.

  • Countries towards the top left – such as Iceland, Australia and Slovenia – are testing extensively, but finding few cases each day.
  • Countries to the bottom right – such as Mexico and Ecuador – are testing much less widely but finding far more cases each day.

Australia: Tests per case: how many tests to find one COVID-19 case?

This chart shows another way of bringing our data on testing together with the data on confirmed cases.

The chart answers the question: How many tests does a country do to find one COVID-19 case?

Here we show how the daily figures have changed over time as the extent of testing relative to the number of new confirmed cases goes up or down.

  • Most countries initially see a fall in the ratio, as their outbreaks grow.
  • Some countries – for example Taiwan and South Korea – have been able to maintain a large number of tests for each confirmed case throughout their outbreaks.
  • Other countries have seen the ratio has fall to very low levels – more than two orders of magnitude lower – where a case is found for every few tests they do.

How to interact with this chart

  • As before you can add and compare any selection of countries using the Add country button.
  • If you move both ends of the time-slider to a single point you will see a bar chart for this point in time.
  • You can switch the chart to a linear axis, by clicking on ‘LOG’.

Australia: World map: total tests performed relative to the size of population

This map shows you how the total number of tests per thousand people compares across all countries in our dataset.

How to interact with this chart

  • By moving the time slider (below the map) you can see how testing coverage has changed over time.
  • You can focus on a particular world region using the dropdown menu to the top-right of the map.
  • Hovering over a country lets you see the exact number.

Australia: What is the total number of confirmed cases?

This chart shows the number of confirmed COVID-19 cases.

What is important to note about these case figures?
  • the reported case figures on a given date does not necessarily show the number of new cases on that day: this is due to delays in reporting;
  • the actual number of cases is likely to be much higher than the number of confirmed cases – this is due to limited testing.

→ We provide more detail on these points in the section ‘Cases of COVID-19: background‘.

Five quick reminders on how to interact with this chart

  • By clicking on Add country you can show and compare the data for any country in the world you are interested in.

Australia: Total confirmed cases: how rapidly have they increased compared to other countries?

The trajectory for every country begins on the day when that country had 100 confirmed cases. This allows you to make comparisons of how quickly the number of confirmed cases has grown in different countries.

Keep in mind that in countries that do very little testing the total number of cases can be much higher than the number of confirmed cases shown here.

How you can interact with this chart

Clicking on any country in the chart highlights that country. If you click on several countries you can create a view in which you can compare several countries.

Any country you might not see immediately you can find via the ‘Select Countries’ in the bottom left. Just type the name in the search box there.

Australia: What is the daily number of confirmed cases?

The previous charts looked at the increase of total confirmed cases – this chart shows the number of confirmed cases per day.

Again you have the option to switch to the rolling three-day average via the link below the chart.

How you can interact with this chart

  • Add countries: add and compare any selection of countries using the Add country button.

Australia: Confirmed cases: How did the total and daily number change over time?

The previous charts allowed you to compare countries.

This is a chart that is helpful to understand the spread of the disease in a single country.

In yellow you see the number of daily new confirmed cases and in red the total sum of confirmed cases.

How you can interact with this chart

On these charts you see the button Change Country in the bottom left corner – with this option you can switch the chart to any other country in the world.

Australia: Daily confirmed cases: are we bending the curve?

To bring the pandemic to an end, every country has to bring the curve of daily cases down to zero.

This chart allows you to track whether countries are achieving this or not.

This chart shows the same data as before, but now adjusted for the size of the population – it shows daily confirmed cases per million people.

How you can interact with this chart

The default log view is helpful to compare the growth rates between countries: on a logarithmic scale the steepness of the line corresponds to the growth rate.

But in this chart, as in many of our charts, you can switch to a linear axis. Just click on ‘LOG’.

Here is an explanation for how to read logarithmic axes.

Australia: Daily confirmed cases: when did countries bend the curve?

This chart shows the number of daily confirmed cases plotted against the total number of confirmed cases.

Plotting the data in this way allows us to see when different countries bent the curve.

How you can interact with this chart

Clicking on any country in the chart highlights that country. If you click on several countries you can create a view in which you can compare several countries.

Any country you might not see immediately you can find via the ‘Select Countries’ in the bottom left. Just type the name in the search box there.

Australia: Weekly cases: where are confirmed cases increasing or falling?

Why is it useful to look at weekly changes in confirmed cases?

For all global data sources on the pandemic, daily data does not necessarily refer to the number of new confirmed cases on that day – but to the cases reported on that day.

Since reporting can vary very significantly from day to day – irrespectively of any actual variation of cases – it is helpful to look at changes from week to week. This provides a slightly clearer picture of where the pandemic is accelerating, slowing, or in fact reducing.

The two maps shown here provide figures on weekly confirmed cases: one shows the number of confirmed cases in the previous seven days (the weekly total); the other shows the weekly growth rate.

Three tips on how to interact with these maps

  • By clicking on any country on the map you see the change over time in this country.
  • By moving the time slider (below the map) you can see how the global situation has changed over time.
  • You can focus on a particular world region using the dropdown menu to the top-right of the map.

Australia: Global comparison: where are confirmed cases increasing most rapidly?

Simply looking at the total or daily number of confirmed cases does not allow us to understand or compare the speed at which this figure is rising.

The table here shows how long it has taken for the number of confirmed cases to double in each country for which we have data. The table also shows how the total number of confirmed cases, and the number of daily new confirmed cases, and how those numbers have changed over the last 14 days.

How you can interact with this table

You can sort the table by any of the columns by clicking on the column header.

Australia: World maps: Confirmed cases relative to the size of the population

For the same reason as before – differences in the population size between different countries are often large – it is insightful to compare the number of confirmed cases per million people.

Three tips on how to interact with these maps

  • By clicking on any country on the map you see the change over time in this country.
  • By moving the time slider (below the map) you can see how the global situation has changed over time.
  • You can focus on a particular world region using the dropdown menu to the top-right of the map.

What does the data on deaths and cases tell us about the mortality risk of COVID-19?

To understand the risks and respond appropriately we would also want to know the mortality risk of COVID-19 – the likelihood that someone who catches the disease will die from it.

We look into this question in more detail here and explain that this requires us to know – or estimate – the number of total cases and the final number of deaths for a given infected population. Because these are not known, we discuss what the current data can and can not tell us about the risk of death (here).

Australia: How did confirmed deaths and cases change over time?

So far we focused first on confirmed deaths and then on confirmed cases.

This chart shows both metrics.

How you can interact with this chart

By now you know that in these charts it is always possible to switch to any other country in the world by choosing Change Country in the bottom left corner.You can sort the table by any of the columns by clicking on the column header.

Australia: The case fatality rate

The case fatality rate is simply the ratio of the two metrics shown in the chart above.

The case fatality rate is the number of confirmed deaths divided by the number of confirmed cases.

This chart here plots the CFR calculated in just that way. 

During an outbreak – and especially when the total number of cases is not known – one has to be very careful in interpreting the CFR. We wrote a detailed explainer on what can and can not be said based on current CFR figures.

Government Responses

In this section

To understand how governments have responded to the pandemic, we rely on data from the Coronavirus Government Response Tracker (OxCGRT), which is published and managed by researchers at the Blavatnik School of Government at the University of Oxford.

This tracker collects publicly available information on 17 indicators of government responses, spanning containment and closure policies (such as such as school closures and restrictions in movement); economic policies; and health system policies (such as testing regimes).

Australia: Government Stringency Index

The chart here shows how governmental response has changed over time. It shows the Government Stringency Index – a composite measure of the strictness of policy responses.

The index on any given day is calculated as the mean score of nine policy measures, each taking a value between 0 and 100. See the authors’ full description of how this index is calculated.

A higher score indicates a stricter government response (i.e. 100 = strictest response).

The OxCGRT project calculates this index using nine specific measures, including:

  • school and workplace closures;
  • restrictions on public gatherings;
  • transport restrictions;
  • and stay-at-home requirements.

You can see all of these separately on our page on policy responses. There you can also compare these responses with countries around the world.
