It is the first of eight evolved Cape-class patrol boats to be delivered to the RAN. Prior to Cape Otway, the RAN already operated the Cape-class patrol boats Cape Fourcroy and Cape Inscription.^[1][2][3][4]

It was built by Austal in Henderson, Western Australia, accepted on 23 March 2022 and based at HMAS Cairns in Queensland, where it arrived in June 2022.^[5] The patrol boat's primary duty lies in fisheries protection, immigration, customs and drug law enforcement operations.^[1][2][3][4]

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$324 million. This order was subsequently expanded by another two boats in April 2022, at an additional projected cost of $124 million.^[6] In November 2023, the RAN ordered a further two evolved Cape-class patrols, at a cost of A$157.1 million.^[7]
