I think the question of new residents for the same lease might be covered by the sub-lease conditions: “If a lot is subleased, the sub-lessor must give notice of the sublease, in accordance with this section, to the owners corporation not later than 14 days after the commencement of the sublease.”
However, given that some legislatures choose not to consider Airbnb lets as sub-leases, this would have to be tested at the Tribunal.
It is worth noting, on the other hand, that both NSW and Victoria recognise verbal (i.e. non-contract) rental agreements as falling under their residential tenancies laws.
This is one for the Tribunals, in the first instance, and the way to achieve that is to apply for the appropriate penalties and see what happens. The legal costs of defending that might be enough to deter the revolving door landlords anyway.
