 Each patrol boat has a standard ship's company of 21 personnel, with a maximum of 29.The "Armidale"s 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 "Armidale"s 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.
