11B Tara Street, O'Sullivan Beach SA 5166

O’Sullivan Beach is driven by coastal affordability, steady amenity upgrades and new land releases that let buyers snap up ocean-adjacent blocks without paying the premium of Glenelg or Christies Beach. Buyers are lured by the mix of lifestyle, solid rental returns around $550 per week, quick turnarounds and proximity to new Port Stanvac-stage infrastructure, making it an appealing entry point for families and investors alike. The suburb still carries risk from its industrial past and limited esplanade, but those same factors are shrinking as green buffers, infrastructure and planned 3,600-dwelling precincts lift appeal, while median house prices north of $730k continue to climb, broadly tracking double-digit gains through the last six months.
