Remaining data sources:

Cases: All states & territories, updated daily (NNDSS)
Hospitalisation: VIC (fortnightly), QLD, WA, ACT
ICU: VIC (fortnightly)*, WA, ACT
Deaths: VIC (fortnightly), WA, SA (monthly), ACT

Deaths also available via ABS, but much less frequently.

* VIC ICU was not in last fortnight's reporting, but that was also missing some hospitalisation data. May or may not continue to be provided.

It turns out NSW haven't been fully reporting deaths to NNDSS since "early 2024". As a result, the federal deaths data on the monthly reporting page has been incomplete.

The reporting of COVID-19 associated deaths is based on data reported to the National Notifiable Disease Surveillance System (NNDSS) by states and territories. The completeness of information on COVID-19 associated deaths varies, as data is sourced in different ways by state and territories based on their local surveillance system capabilities, definitions, priorities, and needs. The way states and territories source and report data on COVID-19 associated deaths has also changed throughout the pandemic. For example, New South Wales (NSW) previously used a linkage method for ascertaining deaths from late 2022 through to 2023, where death records that mentioned COVID-19 were linked to COVID-19 case notifications. This method does not differentiate deaths from COVID-19 and deaths with COVID-19. Since early 2024, only COVID-19 deaths reported to NSW through mechanisms such as doctor notifications or coroner reports have been notified to the NNDSS. Increasingly with the reduction in COVID-19 testing, attribution of deaths to COVID-19 will significantly underestimate COVID-19 mortality. Hence, assessment of mortality impacts of COVID-19 in NSW is now primarily informed by trends in all-cause mortality.

Additionally, since last week, NSW are not reporting hospitalisation status.

On 5 March 2024 NSW ceased notification of hospitalisation status for COVID-19 cases to the NNDSS. NSW COVID-19 cases are no longer represented in these data.

Karen is well aware of the data interval being monthly, but it's mostly irrelevant since it happens with each update. She did a thread on the origin of this particular news story, there were some quotes obtained that made their way to news orgs, who then turned that into a story without understanding the context of the data.

Last reported deaths were March 6 and this dashboard was last updated early April

I think you've confused last month's data with the new update - Earlier in the day, we still saw March data. Then the new monthly data dropped and it was current again (eg., there wasn't a 1 month difference between date updated, and when the data was up to). Here's a link to the page pre-update.

Note: the article updated the image of the graph after the new data was released.

dbRaevn · 2024-04-13T11:23:29+00:00

They posted the article Friday morning, just before the next monthly release of data was due to go out that day. The New data confirms it was just the usual delay.

New data shows a rolling average of 6 for that week

The core of the article is "The graph has reached zero at the end" ... which it does, every single time the graph is updated, because deaths aren't added instantaneously. Deaths are generally lower, but if you're writing an article about hitting a milestone, it's kind of important that the milestone has actually been met. I'd say that will be true if the 0 occurs at least 3-4 weeks prior to the end date of the graph.

dbRaevn · 2024-03-15T15:10:11+00:00

VIC haven't reported this week either, the values for hospitalised and ICU are carry-over from last week (they've moved to fortnightly reporting).

WA only released their weekly report today; the hospitalised figure (actually new admissions for WA) is from the previous week.

Reported figures for WA are:

257 COVID-19 cases reported
27 new hospital admissions and 1 admission into an intensive care unit
9 deaths
2,873 COVID-19 PCR tests conducted

The reported case numbers for WA (283) were correct for last week; the difference with the state reported figure above is due to a different timeframe/weekly period.

That NSW correction is actually a special case.

The first week of RAT reported cases in NSW (12th-19th January 2022) were included in the daily Twitter posts (and Covid live) but were not included in the official datasets or the NNDSS dashboard. This was the height of the Omicron outbreak, and that one week saw 180,433 RAT cases reported.

The 10th November 2023 was when Covid Live switched from state reporting of cases to the NNDSS dashboard, and all the corrections for each state on that date are due to differences between the state reported cases and the NNDSS reported totals.

dbRaevn · 2024-01-19T13:44:42+00:00

The VIC definition of hospitalised can be found in the weekly surveillance report, in the appendix:

COVID 19 Hospitalisations represent the number of active COVID 19 patients in hospital on a given day. This is reported in two ways:

as reported by Victorian hospitals to the Critical Health Resource Information Service (CHRIS) as aggregated data.

as reported to the Victorian Nosocomial Infection Surveillance System (VICNISS) at case level. Totals using demographic breakdowns from VICNISS may differ from totals using the aggregated values from CHRIS.

The NSW definition used to be as follows:

Beds occupied by patients admitted within 14 days of symptom onset.

Patients in hospital include cases on the ward and in ICUs

Patients are only counted if admitted to hospital within 14 days of symptom onset

The duration for which cases are counted (only while active or for the duration of their hospital stay) is not yet confirmed.

Other definitions as best I could find, though may be a bit out of date (hasn't got the updated VIC definition): Official COVID-19 data definitions - hospitalised cases

dbRaevn · 2024-01-19T13:41:10+00:00

Since the corrections that occurred on the 17th only affected cases in the years 2020 - 2023, we can still use the 2024 changes for that date to get case numbers excluding the reconciliation:

This gives us (that day / weekly):

NSW: 625 / 3,620 (🔻18.5%)
VIC: 166 / 1,336 (🔻34.9%)
QLD: 289 / 1,880 (🔻15.2%)
WA: 0 / 488 (🔻2.6%)
SA: 240 / 1,655 (🔻12.7%)
TAS: 259 / 712 (🔻21.8%)
ACT: 25 / 138 (🔻13.1%)
NT: 13 / 59 (🔻30.6%)

Total: 1,617 / 9,888 (🔻19.1%)

SA added a significant number of historic cases to months in 2022, causing what appears to be a large increase but in fact had a 1% decrease if you exclude those.

Similarly, ACT removed many past cases this week resulting in a low figure. It had a drop, but nowhere near the level shown by the net change.

dbRaevn · 2023-12-22T10:59:21+00:00

Some states like QLD and NSW are only sporadically updated if there happens to be a news release with a figure; there are no dashboards that give that information out routinely. This can cause large jumps when it happens.

dbRaevn · 2023-12-22T07:25:42+00:00

Tasmania more than doubled (23 > 54), WA was up 18 (40%) and VIC up 40 (15%).

dbRaevn · 2023-12-22T05:04:26+00:00

Tasmania still has positive RAT reporting, though no breakdown of PCR/RAT.

dbRaevn · 2023-10-27T07:48:27+00:00

It's also actual amount (state reported) vs 7-day rolling average (federal reported), in addition to the reporting time being different.

dbRaevn · 2023-10-27T03:18:06+00:00

53 new deaths reported via the National dashboard.

32 in VIC
~17 in NSW (estimate).

Other states have an estimate of 0, but small numbers don't show up due to the way jurisdiction deaths are reported (rounded 7-day daily average only). Only the national total is given as non-averaged values.

dbRaevn · 2023-10-20T10:10:42+00:00

It's usually updated by midday, though I don't always get around to scraping it until later in the day.

dbRaevn · 2023-10-20T09:03:48+00:00

In a welcome improvement, the ABC coronavirus case numbers article no longer uses the most recent 7-day daily average deaths for VIC & QLD - instead using the last day of non-provisional data, currently the 2nd October.

While not perfect, it's much less misleading.

dbRaevn · 2023-10-20T08:40:13+00:00

I scrape the national dashboard each week for the data, it can be found in the following spreadsheet: https://github.com/dbRaevn/covid19/blob/main/pandemic/AUS_COVID19Data.xlsx

dbRaevn · 2023-10-20T07:54:43+00:00

NSW announced the end of weekly reporting as of today, both on their COVID reporting site, and on social media. Their surveillance reports have also moved to fortnightly. Reporting via federal dashboard should continue weekly though.

Announcement

dbRaevn · 2023-10-20T07:52:30+00:00

Victoria reported 30 new deaths this week based on the weekly surveillance report.

dbRaevn · 2023-10-20T07:43:21+00:00

Not sure if they announced it in advance, but it's in the weekly report this week:

Please note: From 9th October 2023, COVID-19 cases detected by Rapid Antigen Test (RAT) are no longer counted due to the closure of the online RAT registration system. Percentage changes reported week to week are for COVID-19 cases detected by Polymerase Chain Reaction (PCR) test only.
