Start by checking your lease and state or territory tenancy rules for notice periods, break-lease fees and any approved reasons for ending early. Tell the property manager in writing, ask for a written estimate of possible costs, and keep copies of all emails and notices. Arrange inspections, cleaning, repairs, meter readings, key return and a forwarding address, then document the property’s condition with dated photos. Ask how the bond will be handled and whether you can help find a replacement tenant. For tailored guidance or a dispute, contact your state or territory tenancy authority or a tenants’ advice service.
