Two things about Sunshine Beach set the maintenance job. The first is position: the suburb runs from the surf line up a steep escarpment, with no meaningful buffer between the water and the front rows of housing. The second is who is looking after the pool. With 30.8% of occupied dwellings rented — the highest of the four suburbs in this pack — and 35.5% of private dwellings unoccupied on Census night, a real share of these pools are being managed rather than lived with.
Those combine badly. Salt aerosol shortens equipment life, wind-blown sand and shed vegetation load the filter, and evaporation strips heat off the surface faster than owners who have heated an inland pool expect. Meanwhile the person who would notice the early signs is often not there.
So the useful stock here is not the cheapest equivalent. It is the part specified for a marine environment, the cell cleaner for a chlorinator that has scaled rather than worn out, and the cover that does at least as much work as the heater it sits alongside. And the useful advice is what to check on a schedule, because on an exposed pad nothing announces itself.
