An unidentified vessel floated onto a reef near Mount Ernest Island, where some of the crew members were massacred. The sole remaining occupant remained on the vessel, which drifted free at high tide and ran aground on Mount Ernest Island. The sole remaining occupant was massacred, and the vessel was looted. In 1929, the rudder of the vessel and other scattered wooden wreckage was still visible.

Workers erecting a lighthouse were notified by local Aboriginal natives of the presence of a shipwreck some four miles from Breaksea Spit. The wreck site consisted of a timber hull buried upside down in the sand, along with various sundry items including a tea chest, bars of soap, a portion of a box of candles and several bottles of gin. The wreck was never identified.

The remains of a 19th-century wooden sailing ship were exposed during a storm in 1976 between Rainbow Beach and Inskip Point. It is believed to be the remains of the barque Saint Magnus, which drifted ashore in a storm during 1875. The wreck was recently exposed during a storm in 2002-2003.

A fisherman discovered the wreckage of an unidentified shipwreck on the eastern edge of North Ledge Reef. There are no official records of any shipwrecks in that specific location. The debris area is scattered over a wide area, and consists of iron ballast, a cannon embedded in a reef formation. It is surrounded by iron fittings, and some 50 metres away from the main wreckage, an iron water tank protrudes above the waterline.

The wreck site lies on the northern side of the island in a depth of seven metres of water. The only possible candidate for this wreck is the twelve ton iron ketch Gertrude, lost on the island in 1912. The wreck site consists of an anchor attached to the intact bow, which protrudes above the waterline at low tide. The hull has iron sheathing and various other structural debris.

The wreck of an unidentified vessel is exposed offshore of Collis Beach at low tide. Parts of the wreck are scattered down a reef slope to a depth of six metres.
