2). The year 1835 was a disastrous year in shipwrecks, there being 16 colonial vessels wrecked in that year. Four of them occurred in D'Entrecasteaux Channel, three in Bass Straits and three on a reef off Madura Island, Java. The Enchantress was wrecked not far from the site of the wreck of convict ship George III in the D'Entrescasteaux Channel. The Enchantress had been attempting to cross the channel at night. The first part of her to strike the cliffs was her jibboom. She went down in deep water and only three out of a total company of 50 were saved. - Central Queensland Herald 27 October 1932
