You might consider starting a wiki-thread to get other Australian iNatters to help compile a list of species with statuses that need to be updated. There are a few wiki-type threads on here, usually tutorials, e.g. How to use iNaturalist’s Search URLs - wiki or Computer vision clean-up - wiki, which is probably a very similar format to what you would need.
I’m guessing that each country does things a bit differently, but the Canadian iNat team compile the list of taxa requiring geoprivacy and then they solicit feedback using the forum: Updates to taxon geoprivacy and conservation statuses in Canada.
Also, welcome to the forum!
