The Rockingham Wreck Trail, also called the Churchill Park Dive Trail, is Perth's busiest dive site and where many WA divers did their training. It began to take shape around 1987 when Malibu Dive opened in Rockingham, and the steam tug Petrel (1895) was scuttled here in 1985. Over the years clubs and dive shops added small boats, aircraft, steel frames and tyres, connected by pole-and-rope lines in 10–17 m.

The trail as currently documented includes the timber motor boat MV Target (about 10 m long, sunk 1991, 12 m), the motor cruiser Old Timer (the deepest, about 17 m), a twin-engine Beechcraft King Air (sunk 1998, tail removed, half buried) and a smaller Cessna (1999), both at 12 m, an upright steel chicken coop at 17 m, a collapsed coop at 15 m, and tyre piles at 10 m and 14 m, the larger rising 3 m. Older lists also name the Unsinkable, the Luna Sea and the Petrel. Storms in the mid-2000s buried or broke up several items, so the trail changes over time.

The structures are heavily encrusted with soft corals and sponges and are prime habitat for macro life. The chicken coop is known for seahorses, and divers also find octopus, cuttlefish, wrasse, blennies, eels, crustaceans, rays and, in winter, Port Jackson sharks.

The drawback is visibility. Silt and heavy use mean 2–5 m is typical, and visibility worsens as the day goes on. On a quiet winter weekday it can reach 10 m or more.

The trail suits students, newly certified divers practising navigation, night divers and macro photographers. With permanent lines, a dive flag and shelter from most winds, it is dependable and easy to organise.

In Rockingham, drive to the car park at the end of Flinders Lane beside Churchill Park on the Rockingham foreshore. The entry stairs are marked by a sphere. Walk down to the beach, wade about 60 m and surface-swim out to the marker floats and permanent dive flag roughly 100–150 m offshore, then descend on the lines.

Pole-and-rope lines with surface floats link the wrecks. It is about 50 minutes from the Perth CBD and a few minutes from Rockingham town centre.

Protected from most winds by Cockburn Sound and Garden Island, and from the south by Point Peron; only strong north and north-west winds make it rough. This makes it the standard site when others are weathered out. Visibility averages about 5 m and can exceed 10 m in winter, but it falls through the day as divers stir the silt, so dive early, and avoid weekends if possible.

The summer sea breeze roughens the surface swim in the afternoon.

Descend on the marker lines at about 10 m near the northern tyre pile and follow the rope trail south: the Cessna and the Beechcraft at 12 m, the MV Target at 12 m, then west to the chicken coops at 15–17 m and the Old Timer, the deepest wreck at about 17 m in the south-west corner. Return along the lines to the shallower features and ascend on a marker line.

Described as Perth's most-dived location: used daily by Rockingham and Perth dive schools, including Perth Scuba and Dolphin Scuba, for Open Water and Advanced training, guided shore dives and night dives.
