This S-61 was manufactured in 1968, probably as an SH-3 Sea King. It was civilianised in Sept 1992 and registered in the USA as N306V. In 1994 it went to South Africa as ZS-HGU, before returning to the US Register. It has subsequently alternated between US and Canadian registry. It was contracted for bushfire-fighting in Victoria, Australia, during the summer of 2008/9 and was based at Warrnambool. It was photographed here at the Australian International Airshow where it made a one-day appearance in the flying display.

This 1989 S-76B was in Australia for the 2009-10 summer fire season, operating as 'Firewatch 76'. In August 2010 it was transferred to the Canadian Register, still operated by Coulson, as C-FIRW.
