HMAS Maroubra (FY.40/MR) was an auxiliary powered cutter that saw operation in both private use and also as a commissioned vessel for the Royal Australian Navy. The ship was built for Hayles Magnetic Island Pty Ltd of Townsville. Maroubra was the third vessel used by Hayles Magnetic Island Ltd in the shipping contract from Darwin to the Victoria and the Daly Rivers, and replaced Maree which, in turn replaced Magneta.
