Healthcare marketing in Adelaide, by clinic owners.

Adelaide's geographic compactness is a marketing asset. The metro is roughly 25 km wide and most patients live within 15 km of the CBD. A 6-10 km catchment radius is realistic for most clinics. That tightness means campaign budgets stretch further than they would in Sydney, even before accounting for the lower CPC.

Adelaide's healthcare community is the most networked of any Australian capital. Practitioners refer between clinics frequently, allied health professionals know each other personally, and the GP referral network for psychology and physio is unusually robust. The marketing implication: a Google Ads campaign that ignores the referral channel is leaving the easier wins on the table. Most Adelaide clinics need the campaign to fill the gaps the referral network can't reach, not to replace it.

Adelaide has the highest median age of any mainland Australian capital (per ABS regional population data; Hobart edged ahead nationally in 2024), which shifts demand toward physiotherapy, podiatry, and home based OT services. Clinics that recognise this and tune their campaigns accordingly outperform those that copy strategies from younger-skewed cities.

Adelaide is the only mainland capital with a single, genuinely dominant CBD catchment. The city sits in a grid, ringed by parklands, with the Royal Adelaide, the biomedical precinct and both major universities lined up along North Terrace, and the Women's and Children's a few blocks away in North Adelaide. Nothing else in Australia is that concentrated. The practical consequence is that an Adelaide clinic can realistically compete for the whole inner metro, which a Sydney or Melbourne clinic simply cannot afford to do.

Beyond the parklands, Adelaide divides into four directions and everyone here uses those words. East through Norwood, Burnside and Glen Osmond. West through Henley Beach, Grange and Glenelg. North through Prospect, Walkerville, Modbury and out to Elizabeth and Gawler. South through Mitcham, Blackwood, Marion and down the coast to Noarlunga and Seaford. Fee tolerance and funding mix differ across them, and the north south split in particular is real: the northern suburbs and the southern coast are two separate campaigns, not two halves of one.

The growth sits at the edges. Mount Barker in the Hills. The Seaford and Aldinga stretch in the south. Angle Vale, Munno Para and Two Wells in the north. These are the parts of the South Australian market where housing has arrived faster than clinics, and they're the parts where a small budget still buys genuine share of voice against very few competing bidders.

And the Hills are their own market entirely. Stirling, Aldgate, Crafers, Bridgewater and Mount Barker sit above the metro on the freeway, and people up there overwhelmingly stay up there for routine allied health rather than driving down. Treating the Adelaide Hills as part of the metro catchment is one of the most common wasted spend mistakes we see in this state, and one of the easiest to fix.
