Sure, to: Count anything which breeds on mainland Australia (plus
presumably Tasmania) or offshore islands” leaves out so many international
migrants that do clearly fit into Charlie’s question about: “How many bird
species are there in Australia” but do not fit into Charlie’s question about “How
many bird species are resident in Australia?” Which are very different
questions. Which is also a different question from Charlie’s question: “How
many bird species have been sighted in mainland Australia and Tasmania.”

I’ve done a quick scan through the IOC list from Scythebill
for Australia. Deleted extinct and introduced species. Counted
anything which breeds on mainland Australia or offshore islands (not including
Lord Howe, Norfolk, Macquarie etc.).

A partial answer to your questions:
Lists the totals seen by those Australian Birders who choose
to register their totals. Richard Baxter has seen 908 species on Mainland
and islands, and 810 excluding the islands. Mike Carter has seen 902 in
total, and 858 excluding the islands.

Hi all,
I had a few questions regarding the number of bird species in Australia.
How many bird species have been sighted in mainland Australia and Tasmania (but
excluding islands / territories like Christmas Island, Norfolk Island and Heard
Island, etc.).
How many bird species are resident in Australia?
Is a bird considered a resident even if they visit for a few months (e.g.
Papuan pitta).
How many bird species are there in Australia excluding vagrants (that have only
been seen once or a few times such as Eurasian hoopoe last sighted in Broome in
2015).
Would love to hear everyone’s thoughts.
Warm regards,
