Victoria has approximately 220,000 residential swimming pools, with highest density in inner eastern Melbourne (Toorak, Armadale, Malvern, Hawthorn, Kew, Camberwell, Brighton), bayside suburbs (Brighton, Sandringham, Beaumaris, Hampton), and outer east (Templestowe, Doncaster). Melbourne's temperate climate means most pools are seasonal — the swimming season runs October to April, with peak demand from November through March.
Professional pool cleaning manages water chemistry (pH, chlorine, alkalinity, stabiliser, calcium hardness) that goes wrong quickly in warm weather. An algae outbreak requiring shock treatment can cost $300–$500 to fix; regular maintenance at $60–$120 per visit is far cheaper. Melbourne's cooler winters mean many pools are left dormant June–September, but chemistry still needs monitoring during off-season to prevent algae establishing before the spring restart.
Bayside and coastal pools in Brighton, Sandringham, Port Melbourne, and Elwood face additional saltwater influence on chemical balance. Strata and Owners Corporation properties (apartment complexes in Southbank, Docklands, CBD) have specific access and documentation requirements under the Owners Corporations Act 2006 (VIC) for any pool maintenance work on common property.
