Is corporate accomodation the same as short-term letting?

A new owner in a block of four two-bedroom units is an out-of-state company that is expanding its business to NSW, who are using the unit ostensibly as temporary digs for their interstate execs and employees as an alternative to hotel accommodation. It’s essentially unpaid short-term renting. People come in ones or two or more and stay a few nights, maybe a week. Also relatives and friends of the company’s owners have stayed there for an interstate holiday. As expected, problems similar to those caused by Airb’nbers have resulted – sometimes the visitors are noisy, they don’t know or follow the strata rules regarding garbage bins, recycling etc. Just wondering if this sort of tenancy is legal or permissible under NSW strata laws?
