Rottnest Island, WA
The Macedon, a 64-metre coastal steamer, struck the reef in heavy weather and broke up over the following decades. Today the wreckage is scattered across a sandy-limestone bottom: the boiler stands proud at the centre, the anchor is intact, and twisted hull plates and machinery are spread across the site. Marine growth has built up encrusting sponge and weed, and the wreck shelters schools of sweep and bullseyes. Shallow depth and sheltered conditions make this a beginner-friendly wreck dive.
