Queensland Consolidated Acts(1) If the tenant attaches a fixture, or makes a structural change, to the premises without the lessor's agreement, the lessor may--
(a) waive the breach; and
(b) treat the fixture or change as an improvement to the premises for the lessor's benefit.
(2) The lessor may take the action under subsection (1) instead of taking action for a breach of a term of the residential tenancy agreement by the tenant.
