(RAN) acquisition program intended to supplement the navy's mine warfare capability with civilian vessels that could be quickly converted into minesweepers. Vessels acquired under COOP were not commissioned into the RAN, and instead operated with the prefix "MSA" (Minesweeper Auxiliary).

Acquisitions

COOP was initiated in 1985, to cover the gap in mine warfare capability caused by the decommissioning of the Ton-class minesweepers and delays in building their replacements, the Bay-class minehunting catamarans.Jones, in Stevens (ed.), ''The Royal Australian Navy'', p. 252 In order to equip the auxiliary vessels, the RAN acquired several Klein Type 590 towed sidescan sonar arrays, along with Mini-Dyad magnetic influence sweep arrays, AMASS influence sweep arrays, and mechanical minesweeping gear.Wertheim (ed.), ''The Naval Institute Guide to Combat Fleets of the World'', p. 23 When the Bays were found to be poorly suited for minehunting work, the COOP vessels were kept on until the ''Huon'' class entered service, with some retained even later as a supplementary force. Six vessels were purchased under COOP: and (ex tuna fishing boats), (a lighthouse tender), , and the ''Bandicoot''-class minesweepers ''Bandicoot'' and ''Wallaroo'' (former Singaporean harbour tugboats).Gillett, ''Australia's Navy'', p. 44 Another three trawlers, ''Salvatore V'', ''Waverider'', and ''Carole S'', were chartered. Also acquired under the program were three drone ships, which could be operated from the auxiliary minesweepers.Wertheim (ed.), ''The Naval Institute Guide to Combat Fleets of the World'', p. 24 Although not directly a part of COOP, the Defence Maritime Services training ship '' Seahorse Horizon'' can also be fitted out as an auxiliary minesweeper.

End of the program

By 2012, most of the vessels have been sold or returned to their owners. ''Bandicoot'' and ''Wallaroo'' have not been operated as minesweepers since 2010, but were retained until 2014 to provide berthing support for nuclear-powered warships.Saunders & Philpott (eds.), ''IHS Jane's Fighting Ships'' 2015–2016'', p. 25 The drones have been non-operational since 2007, and are due to be replaced by 2013.Gillett, ''Australia's Navy'', p. 42
