21 Carnamah Road, Austral NSW 2179

Modern double-storey build | high-yield granny flat potential | strong suburb growth | premium school catchment The property at 21 Carnamah Road sits within a newly developed pocket of Austral where the street pattern of high-coverage lots with attached granny flats has established a clear rental-income advantage. For a buyer, the key competitive edge here is configuration: a house likely built post-2023 on a 280–300m² lot, matching neighbours that achieve near-maximum site coverage with a separate dwelling. This dual-income structure, combined with the suburb’s 8.3% annual growth and $950/week rent on a comparable 5-bedroom, positions the property as suited to an investor seeking yield-plus-capital-gain or an owner-occupier wanting to offset mortgage costs. The catchment for Austral Public School and Hoxton Park High School adds a stable demand base. The main risk is pricing uncertainty given no direct sales history for this lot; the interpolated value range of $900k–$1.3M reflects a wide spread between a dated sale at 25 Carnamah Road ($560k in 2023) and the premium finishes at 11/11A ($1.45M+). A buyer should verify build quality and whether the granny flat is separately titled or approved, as council compliance affects rental legality. The opportunity lies in the street’s uniformity: if this property is a recent build with modern specifications, it benefits from the same growth trajectory as neighbours, and the lack of bushfire or flood risk reduces insurance overhead.
