Acute was predominantly used for training of Royal Australian Navy Reserve personnel at Fremantle, Western Australia. From November 1978 until the 1980's, Acute was attached to the Permanent Naval Force, and was assigned to the newly completed base at HMAS Stirling.
Whilst on a training cruise in May 1983, Acute apprehended two Taiwanese fishing boats engaged in illegal fishing. This was the first such operation involving RANR personnel.
Acute paid off on 6 May 1983. She was transferred to the Indonesian Navy and renamed Silea. The patrol boat was listed in Jane's Fighting Ships as still operational in 2011.
