This engaging museum tells of Jervis Bay's ship-building past and Aboriginal history. Interesting displays explain the Wreck Bay Aboriginal community's struggle for land rights. Back rooms are filled with imagination-firing maritime miscellany like brine-splashed wooden chests and ship figureheads. The gardens, laid out like an old ship-building yard, are fun to ramble.
Clambering aboard the heritage-listed 1912 Lady Denman ferry is a highlight; explain to kids that they'd be in the engine room, while grown-up passengers would occupy the much-nicer saloons.
The Lady Denman chugged to and fro in Sydney Harbour in the early 20th century, but she was born (and retired) in Jervis Bay, and remains a symbol of the local ship-building industry.
The local visitor centre is on-site, along with a very good souvenir shop selling Indigenous-made gifts.
