Now that DHA have published their July 2020 189/491 invitation results we can see some more clarity
https://immi.homeaffairs.gov.au/visas/working-in-australia/skillselect/invitation-rounds

500 invitations were given for the 189 round and 100 for the 491 (family sponsored) round.
It looks like the 491 round was run first and hence we had the unusual result of a massive 48 invites given for the 2335 group. This is a result of the backlog of many 491s in that category that have not received an invite for many months and suggests no occupational quota was enforced on that July 491 round. So when the 189 round was then run , in fact it is likely no invites were received for the 2335 group as they more than had enough invites in the 491 round.

Also around 400 of the invites were given for the NON PRO RATA occupations and around 100 for the PRO RATA occupations. This likely a result of them only inviting occupations that are considered critical to the COVID19 recovery.

From what we can see those occupations that have been flagged as being able to receive invites at the moment are the following

Finally the occupational ceilings were announced for 2020/21 and they are here

Note that does NOT mean this is the amount that will be invited for each occupation, it is simply a ceiling that cannot be exceeded.

The number of Accountants falling to 1000 is very disappointing. All other occupations look to have been slightly adjusted to match a figure equal to 6% of the number of total people employed in that occupation in Australia
