The Aquarium of Western Australia (AQWA) is a privately owned aquarium in Hillarys, Western Australia. Located approximately 20 km (12 mi) north-west of Perth at Hillarys Boat Harbour, it is a popular attraction for both tourists and locals.

AQWA was Australia's largest aquarium when it opened and still possesses Australia's largest single aquarium and underwater tunnel, the 3 million-litre Shipwreck Coast exhibit. As of 2025, AQWA houses over 45 unique displays showcasing native Western Australian marine life and living corals, many of which are endemic to WA's waters.
