Tennent’s Treasure: Some bushranger buffs claim that squirreled away in a cave on the slopes of Mt Tennent is the buried booty of bushranger John Tennant who supposedly hid on the mountain before his capture in 1828. One of Tennant’s biggest heists was on November 21, 1827 when he cleaned out overseer James Ainslie’s cottage at Duntroon of basic provisions including “one plain handkerchief, three red shirts, 150lbs of flour, trousers, 1 pair of half boots … four holey dollars, three Spanish dollars and two rupees.” Those holey dollars would be worth a fortune today.
