In Perth, ending a fixed-term tenancy early may leave you responsible for the landlord’s reasonable, proven losses, such as rent until a new tenant moves in and reasonable advertising or re-letting costs. The landlord must generally take reasonable steps to reduce their loss, and you should not assume a blanket “break lease fee” is automatically enforceable. Discuss the situation with the landlord or property manager in writing, check your agreement, and keep records of any payments and communication. For current notice rules and dispute help, see Consumer Protection WA’s tenancy guidance or seek independent legal advice.
