1 Crystal Harmony Court, Sellicks Beach SA 5174

Sellicks Beach’s demand is fuelled by its coastal lifestyle, affordability relative to the metro fringe, and the new masterplanned community rezoning that keeps it on buyers’ radar while still feeling accessible. Prices continue to trend up, with the median house now near $870k and the suburb recording roughly 2.7% growth over the past quarter after a double-digit lift over the year to January 2026. Growth upside rides on the rezoning and planned infrastructure, but risks remain in the environmental pushback around Aldinga Washpool, stormwater costs and the pace at which new supply can be absorbed.
