Venture into the secret world of submarine warfare on HMAS Onslow.

Our submarine was decommissioned in 1999, just weeks before coming to the museum. It's still close to operational condition. So, if you go onboard, listen out for the diving alarm!

With 5 other Oberons, Onslow gave the Royal Australian Navy a formidable submarine force. The motto of the navy's submarine arm is "Strength, silence, surprise".

This explains many of Onslow's characteristics, including:

  • a diving chamber for Special Forces to leave the boat for covert operations
  • a gash ejector containing weighted rubbish (gash) bags. When ejected, the bags sink to the ocean floor so no debris floats to give away the submarine's position
  • soundproofing on all equipment to make Oberons one of the quietest class of submarines ever built.

Onslow has travelled the equivalent of more than 16 times around the world, serving Australia with quiet distinction for 30 years.

"How amazing was the submarine!?!...apart from a few occasions of feeling a little anxious about the closed in space, it was so very interesting. I've never seen so many valves and buttons. How they know what each one does is unbelievable."

"One guide today on the submarine in particular was wonderful although all the guides on all the boats were knowledgeable and extremely kind to our three-year-old son today. Highly recommend and thank you."
