Primarily a grassy location, there are three memorial brush box trees close to the pedestrian path, each with a small sandstone plinth and with plaque commemorating one of three lost ships - HMAS Sydney II, HMAS Perth and HMAS Canberra. The original tree planted for the HMAS Canberra died in 2004 and has been replaced. There is also a memorial honouring the memory of those who served on the four HMAS Sydney ships. This monument consists of four circular bronze plaques set within a square consisting of pink and white granite divided by a cruciform axially aligned with the memorial mast. The cruciform is created by four raised long pink granite name plates, one each for the four Sydney ships. Nearby is a stone column from the old Sydney Post Office which is a distance of precisely one nautical mile from the tower of Fort Denison. To the north is the 1905 offshore electric beacon and foghorn originally powered by a submarine cable from the Fort Macquarie electric light station.
