The J7 Submarine at Sandringham Yacht Club is a unique visible feature of the marina, and is historically significant as one of the Royal Australian Navy's earliest submarines, predated only by the AE-1 and AE-2.

The J-7 differed from the other J-class submarines. The J7's submerged displacement of 1,760 tons was 60 tons less than that of her sister boats. The control room was repositioned further aft by circa 60 ft (18 m), between the main engine rooms. The conning tower moved with it. The 3-inch HA gun was mounted in a lower position at the forward end of the superstructure.
