Due to the difference in reporting times between states, territories and the federal government, it can be difficult to get a current picture of how many confirmed cases of coronavirus there are in Australia.
Here, weâ€™ve brought together all the figures in one place, along with comparisons with other countries.
Guardian Australia has gone through every state and territory press release to construct and maintain an up-to-date database of coronavirus cases, as well as maintaining live data feeds from other groups collating data, such as Johns Hopkins University.
This is necessary to get a broader picture of how Covid-19 is affecting Australians and to track the impact of government measures.
This chart shows the â€œepidemic curveâ€ for Australia with a timeline of measures introduced by the federal government. It aims to track our progress in â€œflattening the curveâ€, and the measures we have introduced to do so.
Most of the recent national growth is due to cases from Victoria.
The following chart shows the percent growth in cases, with a trend line based on a five-day average. Generally, we want both lines to be heading downwards towards zero:
Here, you can see the cumulative total of confirmed cases, with the contribution of each state and territory:
Since mid-June, Victoria has had a rise in community transmission of Covid-19. This has resulted in the Premier, Daniel Andrews, re-introducing physical distancing restrictions that had been previously lifted.
Here, you can see the total number of daily cases, split by those where the source of the infection was overseas, and those where it was acquired locally or still under investigation.
Here, you can see the trend in the source of Covid-19 cases over the whole length of the coronavirus pandemic in Victoria:
Hereâ€™s a more detailed breakdown for recent cases only, showing the number of cases each day that are from a known or unknown source, as well as those that are under investigation:
As the Victorian government increases testing, we might expect to see a rise in cases. This chart shows the percentage of positive cases per the number of tests conducted for both Victoria and NSW. A lower % positive rate is indicative of more widespread, less-targeted testing.
Generally the % positive rate in Australia is lower than many other countries, well below the threshold that the WHO has reccomended for adequate testing.
The recent outbreaks are related to specific locations, with hotspots in Melbourneâ€™s outer suburbs:
State and territory breakdowns
Here is the daily count of confirmed cases â€“ the epidemic curve â€“ for each state and territory. The most recent day will usually be an incomplete total:
This table has the number of deaths for each state and territory, as well as the number of patients requiring hospital treatment. It also includes the number of patients currently in intensive care, or requiring ventilators.
Source of infections
This chart shows the daily new case count by the source of infection to compare overseas v local cases. Itâ€™s important to also note that a large number of cases are under investigation at any point in time, and so these figures can change retrospectively with further updates.
Maps of confirmed cases in NSW, Qld and WA
These maps now show recent cases only, and there are now very few recent cases in most states outside of Victoria and NSW.
Hereâ€™s the map for Queensland, mapped by hospital and health service regions:
And the map for Western Australia:
Here, you can see the testing rate per million people for each state and territory:
You can see an earlier rough comparison of these rates with other countries here.
This chart uses a log scale and re-indexes the time to the first day since cases were above 50 to make the trajectory of the pandemic in selected countries directly comparable:
This chart uses a similar view to compare the trend in deaths for the same countries:

- Added testing % positive chart for Victoria and NSW
- Added new chart of Victorian cases by source
About the data
This database is available for reuse under a Creative Commons Attribution 3.0 Australia (CC BY 3.0 AU) licence, which means it is OK to re-use, but please provide attribution and a link to Guardian Australia. The data is available in Google sheets here or as a JSON feed here.
We assign cases to the date on which they were reported by the given health department, and deaths are assigned to the date they occurred. Extended data on testing and demographics varies between each state and territory so may not always be available. Please contact email@example.com if you spot an error in the data or to make a suggestion.
Due to the nature of collating data daily under time pressure and differences in how data is collected, we recommend cross-checking with other data sources where possible. It is quite likely these figures will vary from other figures due to differences in data collection methods.
