Row's preparations for the Treasuries landings suffered from a lack of shipping, which was prioritised for the upcoming landings on Bougainville but despite this, on 27 October, the brigade's 29th and 36th Battalions landed on the south coast of Mono Island, while 34th Battalion landed on the much smaller Stirling Island while a company from 34th Battalion and US construction engineers landed on the north coast on Mono to establish a radar base there.
