Shamrock was the last ferry built by the Joubert's for their Lane Cover River operations. She was also the biggest and fastest of these ferries.

She passed to the Balmain New Ferry Company when they aquired the Parrammatta and Lane Cover River routes but was not sold to Sydney Ferries Ltd in 1917 when that company took over most of the remaining ferry companies.

She was instead sold to Newcastle and renamed Wattle. She operated the Stockton route until being broken up in 1941.
