HMAS Boonaroo

HMAS Boonaroo (also known as MV Boonaroo) was an Australian National Lines cargo vessel used to support Australian forces fighting in the Vietnam War. She was the first Australian ship to be commissioned after the introduction of the Australian White Ensign.

Construction and civilian history
Boonaroo was constructed for Australian National Lines by Mort's Dock and Engineering in Sydney. The ship was completed in 1953, and operated as a merchant vessel until she was chartered by the Department of Shipping and Transport in 1966 to carry Australian soldiers and supplies to Vietnam. She completed one voyage to Vietnam as a merchant vessel, leaving on 17 May 1966 and arriving back in Australia on 8 July 1966. However, the Seamen's Union of Australia refused to crew the vessel for subsequent voyages in protest against Australia's involvement in the conflict.

RAN service
To keep the ship operational, she was commissioned into the Royal Australian Navy (RAN) on 1 March 1967, and became the first Australian ship to be commissioned under Australian White Ensign. The crew was replaced by RAN personnel, and departed Port Wilson, Victoria on 10 March with a cargo of munitions for the Royal Australian Air Force and general cargo for the support and establishment of Australian forces in Vietnam, including prefabricated kitchen structures, telegraph poles, and a fuel tanker.

Boonaroo arrived in Cam Ranh Bay on 28 March, and over the next five days was unloaded, leaving Vietnam waters on 3 April. She arrived in Sydney on 29 April. The cargo ship left Sydney for Melbourne on 3 May, arrived on 5 May, and was decommissioned from RAN service on 8 May. Boonaroo was returned to Australian National Lines.

Following a reorganisation of RAN battle honours, Boonaroo was retroactively awarded the honour "Vietnam 1967".

Later career and fate
In January 1971, she was sold to Collin Navigation Co., S. A. Hong Kong and renamed Collin Four and in 1972 transferred to a subsidiary company. The ship was sold to Uni-Ocean Lines Pty Ltd, Singapore in February 1976 and renamed Reunion and again sold in November 1977 to United Orient Lines Ltd, Singapore.

She was scrapped at Chittagong, Bangladesh in November 1985.
