Here is the list of ADI approved banks: https://www.fcs.gov.au/which-adis-are-covered
Each bank has a $250,000 guarantee per customer per organisation (For example Bankwest and CBA are the same org so only one lot of $250k is covered).
And here is type of accounts covered https://www.fcs.gov.au/which-bank-accounts-are-covered-under-fcs
So all seems OK up to $250k on an offset account.
