States and territories will no longer publish COVID-19 case numbers daily, moving to weekly updates on new infections.
The decision follows a meeting of health ministers last Friday, but was not made public until Wednesday.
The weekly figures, to be consistently reported across jurisdictions, will include case numbers, new and total deaths, vaccination rates and hospital data, which will contain a breakdown of ICU and ventilated patients.
Federal Health Minister Mark Butler said health officials had backed the changes.
"The move is supported by chief health officers and will ensure high quality, accurate information is provided that sheds more light on COVID dynamics," he said in a statement.
"This approach will bring national reporting in line with all the state and territories and support the analysis of COVID trends nationally and globally.
"The national report will be expanded to include trends-based analysis and oral antiviral treatment uptake."
ACT Health Minister Rachel Stephen-Smith said cases had slowed in the territory, which will move to weekly reporting on September 16. The final daily case numbers report will be issued on Friday.
"The winter wave of COVID-19 has passed and we have reached a stage in the pandemic where daily reporting is not as important as it was," she said.
"Weekly reporting will allow the public to stay informed about the level of COVID in the ACT and the impacts it is having on our health system and society more broadly."
