.. and here's an interesting snippet from the ANZIS survey of all 194 private and public ICU's:

The total number of currently open staffed ICU beds was 2,183 as at 31/8/2021. This was 195 fewer (8.2%) than in 2020; the decline was greater for rural/regional (18%) and private ICUs (18%). The reported maximal ICU bed capacity (5,623) included 813 additional physical ICU bed spaces and 2,627 in surge areas outside ICUs. The number of available ventilators (7,196) exceeded the maximum number of ICU beds. The reported number of available additional nursing staff would facilitate the immediate opening of 383 additional physical ICU beds (47%), but not the additional bed spaces outside ICUs.
