A detachment of aircrew and maintenance personnel from RAAF's No. 1 Squadron is currently at Naval Air Station Lemoore in California, preparing the aircraft for the series of flights to Australia.
The detachment is conducting acceptance flights and ground tests on each of the aircraft.
The group of four Super Hornets, fresh off the Boeing production line, will be accompanying Air Force One from the US when US President Barack Obama visits Australia next month.
Another key task for the detachment will be working with an air-to-air tanker, conducting day and night refuelling flights to ensure they are ready for the journey to Australia.
The Air Force is acquiring 24 Super Hornets which will progressively arrive at their home base, RAAF Amberley near Ipswich, during 2010 and 2011.
The Super Hornets are an interim replacement for the ageing F-111s.
The F-111s have served Australia well, but are now approaching the end of their operational life, and will be retired at the end of this year.
