Data analysis by the Ripehouse research desk · Reviewed by Anna Cooper, Co-Founder & COO, former Managing Editor of Australian Property Investor Magazine
Is Sellicks Beach (SA 5171) a good suburb to invest in 2026? Our October 2026 quantitative audit scores Sellicks Beach at 94/100 (Ranked #927 of 15,286 suburbs), with a $953,000 median house price (+9.5% 12m), $1100/wk rent (6% yield), and 0 top-tier streets scoring 75–100/100.
Market Classification: Acute Rental Squeeze & Yield Expansion Market · R-Score: 94/100 (National Rank #927 of 15,286) · Street Average: 50/100 across 74 streets.
A balanced Australian rental market sits around 2.5% vacancy; Sellicks Beach is currently operating at just 0.5% vacancy. When rental stock is this scarce, properties lease within days, weekly asking rents ($1100/wk) face sustained upward pressure, and local renters who can afford a deposit begin transitioning into first-home buyers—putting a floor under established house prices.
“I would not let the 6% gross yield do all the talking here. At an $1,100 weekly rent, the numbers look strong, but the stated 80% LVR cash flow is still negative $18 a week. I’d verify achievable rent and total holding costs before comparing properties.”

2. The “Two-Speed Suburb” Test: Best & Worst Streets in Sellicks Beach (SA)
Why do two 4-bedroom houses in Sellicks Beach achieve completely different bank valuations and tenant quality? Because suburb medians blend every pocket together. When we map all 1,932 addresses across 74 streets in Sellicks Beach through G-NAF to their ABS 2021 Census SA1 blocks, the suburb splits into three distinct tiers:
- Strong Street Profile (Score 75–100): 0 streets (0% of scored streets) pass both ABS Census tenure tests (owner-occupiers >65% and public housing ≤5%) plus at least one—or both—of the Sellicks Beach rent and yield benchmarks.
- Mid / Mixed Street Profile (Score 50–74): 52 streets pass the core owner-occupier and public-housing thresholds but sit below the suburb median on weekly rent or yield.
- Weaker / Caution Street Profile (Score 0–25): 0 streets fail one or both census tenure thresholds—meaning either owner-occupation sits at or below 65% or state/community public housing exceeds 5% on those specific SA1 blocks.
