At the 2021 Census, 82.2% of Tewantin's occupied dwellings were separate houses — the highest share of the four suburbs in this pack, against 56.9% at Sunshine Beach — and just 7.3% of private dwellings were unoccupied, against 37.6% at Noosa Heads. Median household income was $1,263 a week, the lowest of the four.
Read together, that describes owner-maintained pools at permanently occupied houses, on a budget that makes a repair genuinely preferable to a replacement. It is the opposite of the beachside pattern, where the pool has to be presentable for someone else on a fixed date.
A lot of these pools were also inherited rather than chosen. People buy an established house on a decent block and the pool comes with it — often with no manual, no service history, and an equipment pad nobody can identify. The first useful thing a pool shop can do in that situation is work out what you actually own, because the two expensive mistakes we see most both start there: replacing a whole system when a seal kit would do, and pouring chlorine into a pool whose real problem is a failed filter.
