ADV Cape Woolamai

Australian Defence Vessel (ADV) Cape Woolamai, named after Cape Woolamai in Victoria, is an evolved Cape-class patrol boat of the Royal Australian Navy (RAN).

The ship is the fifth of ten evolved Cape-class patrol boats to be delivered to the Royal Australian Navy. Prior to Cape Woolamai, the RAN already operated the Cape-class patrol boats ADV Cape Fourcroy and ADV Cape Inscription as well as the evolved Cape-class patrol boats ADV Cape Otway, ADV Cape Peron, ADV Cape Naturaliste and ADV Cape Capricorn.

The ship was built by Austal in Henderson, Western Australia, commissioned on 22 June 2023 and is to be based at HMAS Coonawarra in Darwin, Northern Territory.

The ship is one of the original six evolved Cape-class patrol boats the RAN ordered in April 2020 to replace the Armidale-class patrol boats in this role, at a projected cost of A$324million. This order was subsequently expanded by another two boats in April 2022, at an additional projected cost of $124million. In November 2023, the RAN ordered a further two evolved Cape-class patrols, at a cost of A$157.1million.
