He raised the alarm and the authorities found that the boat contained five bags full of clothing, Young's books and papers, a bullet in its starboard side and some vomit. The craft was staved in and there was no sign of the men. Subsequent searches, rewards, government inquiries and wide media coverage turned up the remnants of a fire, some food and three shirt studs. The mystery was never solved. A monument was erected at the site in 1980 to mark the centenary.
Mystery Bay is part of the Dromedary Conservation Area.
It includes seven coastal lakes, a number of beaches and Montague Island. Mystery Bay is a popular camping site for anglers and a launching site for Montague Island while the deep waters off Cape Dromedary are ideal for kingfish and bonito. There are a number of excellent lookouts around the township - particularly off Paraboon Drive. The best way to enjoy the dramatic cliffs and the beautiful honey-coloured rocks is to drive around the foreshores. The lookouts are clearly marked and all offer excellent views.
