Cabin on P.S. Gem, at the Swan River Pioneer Settlement.
From information panel:
For all her luxurious fittings elsewhere, the cabins on the Gem were simple and straightforward, if not a little on the small size. It was joked that cabins were kept deliberately small in order to reduce the number of mosquitoes that had to be killed before settling down for the night. Not all passengers had even this level of comfort in their accommodation; deck passengers essentially purchased only standing room on the passenger deck. They would have to find their own berth for the night, usually an uncomfortable one, lying on the deck cargo of wool bales. barrels or crates. At least the crew had folding bunks!
