Most commercial leases are subject to similar real estate laws from state to state. The exception concerns retail rental agreements under national/territorial retail rental law. If the duration of this lease is longer than three years, it must be registered. A sublease that has been removed from a registered head lease should be registered by itself. In June 2016, the Supreme Court of Victoria ruled in favour of a landlord in an unprecedented case. It was found that the tenants had breached their agreement by using the property as AirBnB, as it was a sublease agreement. This is expressly prohibited in the rental agreement without the consent of the owner. At the time of the letter, the law still needed to be adapted to include AirBnB`s agreements in the Residential Tenancy Act. .
