HMAS Wollongong (ACPB 92)

HMAS Wollongong (ACPB 92), named for the city of Wollongong, New South Wales, is an Armidale class patrol boat of the Royal Australian Navy (RAN).

Design and construction
The Armidale class patrol boats are 56.8 m long, with a beam of 9.5 m, a maximum draft of 2.25 m, and a displacement of 270 tons. The semi-displacement vee hull is fabricated from aluminium alloy, and each vessel is built to a combination of Det Norske Veritas standards for high-speed light craft and RAN requirements. The Armidales can travel at a maximum speed of 25 kn, and are driven by two propeller shafts, each connected to an MTU 16V M70 diesel. The ships have a range of 3000 nmi at 12 kn, allowing them to patrol the waters around the distant territories of Australia, and are designed for standard patrols of 21 days, with a maximum endurance of 42 days.

The main armament of the Armidale class is a Rafael Typhoon stabilised 25 mm gun mount fitted with an M242 Bushmaster cannon. Two 12.7 mm machine guns are also carried. Boarding operations are performed by two 7.2 m, waterjet propelled rigid-hulled inflatable boats (RHIBs). Each RHIB is stored in a dedicated cradle and davit, and is capable of operating independently from the patrol boat as it carries its own communications, navigation, and safety equipment.

Each patrol boat has a standard ship's company of 21 personnel, with a maximum of 29. The Armidales do not have a permanently assigned ship's company; instead, they are assigned to divisions at a ratio of two vessels to three companies, which rotate through the vessels and allow the Armidales to spend more time at sea, without compromising sailors' rest time or training requirements. A 20-berth auxiliary accommodation compartment was included in the design for the transportation of soldiers, illegal fishermen, or unauthorised arrivals; in the latter two cases, the compartment could be secured from the outside. However, a malfunction in the sewerage treatment facilities aboard HMAS Maitland (ACPB 88) in August 2006 pumped hydrogen sulfide and carbon monoxide into the compartment, non-fatally poisoning four sailors working inside, after which use of the compartment for accommodation was banned across the class.

Wollongong was constructed by Austal at their shipyard in Henderson, Western Australia. She was named in February 2007 by Mrs Kylie Heron, wife of Commander Wesley Heron, a former Commanding Officer of the Fremantle class patrol boat HMAS Wollongong (FCPB 206). Wollongong was commissioned into the RAN in Sydney, New South Wales on 23 June 2007; a location closer to her namesake city was desirable, but there was no suitable berth at Port Kembla and she was too large for the Wollongong Harbour entrance.

Operational history
Operationally, Wollongong has spent the majority of her career on border patrol to Australia's north and north-west. The ship is assigned to Ardent Division of the Australian Patrol Boat Group, is based in Cairns, and performs border protection and fisheries protection patrols.

In July 2007, the ship became the first vessel of her class to visit the port of Brisbane, Queensland.

In June 2012, Wollongong was one of several ships to respond to a Suspected Illegal Entry Vessel which sank with 206 passengers while en route to Australia. The patrol boat transported the 109 survivors found during the initial rescue operation to immigrant processing facilities at Christmas Island.
