MSA Brolga in 2001. Brolga was a lighthouse tender acquired by the RAN under the Craft of Opportunity Program to serve as an auxiliary minesweeper.

The Craft of Opportunity Program (COOP) was a Royal Australian Navy (RAN) acquisition program intended to supplement the navy's mine warfare capability with civilian vessels that could be quickly converted into minesweepers. Vessels acquired under COOP were not commissioned into the RAN, and instead operated with the prefix "MSA" (Minesweeper Auxiliary).
