Sub Base Platypus

Looking for things to do in North Sydney? Sub Base Platypus is an ideal setting for rest and recreation.

Formerly a torpedo factory, submarine base and gasworks, Sub Base Platypus is a community recreation and work hub in North Sydney, homeland of the Cammeraygal People.

Featuring a shaded BBQ area with seating, a pocket playground and a scenic waterfront promenade, Sub Base Platypus is a place where visitors can relax on the waterfront with friends and family.

Did you know? Despite its name, Sub Base Platypus isn't home to any platypuses! It's believed the Royal Australian Navy chose the name HMAS Platypus due to the similarities between the duck-billed monotreme and submarines. Platypuses use electro receptors in their bills to locate food underwater just as submarines use sonar to detect objects. In 2017, the Harbour Trust rechristened the site Sub Base Platypus.
