The two ALC 50s were built by Phoenix Shipyards in Devonport, Tasmania and were completed in 1962 and collected for sea trials and transfer to Sydney early that year.
The operating unit that accepted and ran them both was 4 Water Transport Troop, Clifton Gardens, Middle Head, Sydney.
The voyage was not without difficulty and sailing through the aftermath of a gale caused conditions that saw th bow door start to "peel" externally, some engine troubles that caused a close-down on one side, one rudder pintle breaking, and the helm-wheel shake to pieces leaving only its steel skeleton.
This unhappy voyage ended with the vessel coming into Sydney Harbour with distress flags/balls hoisted, having to steer in a slow circle to port then a short burst of full astern, in an attempt to get it to dock alongside Clifton Gardens base.
Despite such an eventful maiden voyage, that vessel was fixed in 4 Water Transport's own workshops and all faults repaired, leaving it to go into honourable service as shown below.
