It's About the Journey Not Just the Destination
A modified Pacific Class Patrol Boat, MV Mercator is used by the Royal Australian Navy for navigation training. Based at HMAS Waterhen on Sydney Harbour, she provides training to officers and sailors from the RAN and other navies in coastal navigation, ship handling and watch keeping procedures. She is also utilised to assist Major Fleet Units (MFU) with boarding party training.
Capable of being deployed from the Royal Australian Navy’s Adelaide-class LHDs, the LHS Landing craft (LLC) are equipped with radar navigation, GPS, gyro needle/magnetic and HF communications equipment, VHF and UHF. This enables them to operated over the horizon (greater than 37km) from the shore.
The LLCs are able to transfer men and equipment ashore from the LHDs, including the Australian Army’s M1A1 Abrams main battle tanks.
Sub Base Platypus is a unique site located in Neutral Bay, Sydney, Australia. The site has a rich history dating back to the early 1900s when it was originally used as a gasworks site. In the early 1960s, the site was acquired by the Royal Australian Navy (RAN) and used as a submarine base until it was decommissioned in the 1990s. During this time, the bas was home to the six Oberon class submarines operated by the RAN.
Not only were the submarines themselves based here, but a torpedo factory, maintenance facilities and a school for submariners provided a complete support structure for them.
Although long retired, several of the Oberons still exist as museum displays. HMS Onslow is close by in Sydney at the National Maritime Museum, while HMS Otway sits in Holbrook.
We chose to take public transport because parking in the area is limited. A small carpark on Kiara Close provides somewhere to park if you drive. When we visited, this area was being extended, so perhaps in the future more space will be available.
The closest train station is Milsons Point, so we got off there and walked for only 10 minutes to get to the old submarine base. On the way we passed plenty of cafes and eateries, so grabbing a snack or drink is not a problem.
We entered via an alleyway off High Street, but access is available from Kesterton Park, which has a walkway over the water and an interesting entrance sign. We exited this way, so got to see both. Future plans will have a more official entrance off High Street.
Today, Sub Base Platypus has been redeveloped and transformed into a public space for the community to enjoy. The site includes a range of facilities and features, including a playground, public spaces, and a memorial to submariners who lost their lives in service to Australia.
The playground is a popular attraction for families, with a range of equipment and play areas designed for children of all ages. The playground has been designed to reflect the history of the site, with play structures shaped like torpedoes and submarines. Stepping stones running through the gardens are labeled with the phonetic alphabet (alpha, bravo, Charlie etc.).
In addition to the playground, Sub Base Platypus is also home to the Submariners Memorial, which honors those who served on the Oberon class submarines, particularly the three men who lost their lives while serving. The memorial includes HMAS Oxley’s anchor and the names of the submarines on the steps.
Although currently closed, the old workshops and torpedo factory are, planned to re-open in the future. On High Street, a series of information boards show large photos of operations in these buildings.
Looking ahead, there are plans to further develop Sub Base Platypus into a cultural precinct that celebrates the site’s rich history and promotes community engagement. The development plans include a range of facilities, including a museum, art galleries, and performance spaces.
Overall, Sub Base Platypus is an important and unique site that has been transformed into a valuable community asset. Its history as a submarine base and gasworks site is honored through its public spaces and features, making it a significant and memorable part of Sydney’s cultural landscape.
