The rule: certificate before every new lease
A current pool safety certificate must exist before entering a residential tenancy - and for most short-stay accommodation. Non-shared pools: 2-year certificates. Shared pools (unit complexes): 1-year, held by the body corporate. Both the owner and the property manager can be fined over a non-compliant rental pool, which is why QLD agencies refuse to list without the certificate on file.
Short-stay and Airbnb
QLD treats most short-stay pool properties on the shared-pool footing - a 1-year cycle. Running an Airbnb with a pool means an annual inspection subscription; budget it like pool chemicals.
Renewals and mid-tenancy
A still-valid certificate carries over to a new lease; an expired one must be renewed before signing. Mid-tenancy expiry doesn't force an immediate re-inspection, but the barrier must comply every day and councils inspect on complaint. Tenant reports a dropped gate? That's an urgent repair, not a next-inspection item.
For property managers
Track certificate expiry across the rent roll like smoke-alarm compliance - same recurring model, same liability logic. Bulk arrangements with a single QBCC-licensed inspector across a portfolio are routine and cheaper.
