Among major cities, Perth's coastal suburbs recorded the strongest growth, ranging from 17.8 to 19.3 per cent annually. Mandurah leads at 19.3 per cent ($685,000), followed by Iluka-Burns Beach ($1.67 million) and North Coogee ($2.03 million). This performance reflects Perth's position as Australia's fastest-growing capital city, with coastal appreciation spanning both affordable and luxury price points.
Brisbane's northern growth corridor continues its momentum, led by Mango Hill (16.9 per cent, $1.10 million) and Murrumba Downs-Griffin (16.4 per cent, $1.06 million).
Darwin's top-performing coastal suburbs of Tiwi (16.3 per cent, $658,000), Durack-Marlow Lagoon (15.4 per cent, $687,000), and Brinkin-Nakara (13.9 per cent, $759,000) reflect growing defence sector presence.
Adelaide's growth concentrates in relatively affordable suburbs: Virginia-Waterloo Corner (15.8 per cent, $831,000), Seaford-Seaford Meadows (14.3 per cent, $880,000), and Largs Bay-Semaphore (13.4 per cent, $1.00 million).
Sydney's coastal growth has shifted north to the more affordable Wyong region on the Central Coast. Lake Munmorah-Mannering Park ($841,000), Budgewoi-Buff Point-Halekulani ($863,000), and Toukley-Norah Head ($977,000) all recorded growth around 10.8 per cent, which is modest by national standards but represents some of the last sub-$1 million coastal options in Greater Sydney.
Melbourne recorded the slowest capital city coastal growth, with Frankston (7.9 per cent, $901,000), Seaford (7.5 per cent, $928,000), and Somerville (7.4 per cent, $923,000) all experiencing single-digit appreciation.
