Two of the Australian high mobility artillery rocket system (HIMARS) launchers are on show at Avalon International Airshow.
They were delivered from the US by an RAAF C-17A Globemaster II on March 21.
Defence Minister Richard Marles said the HIMARS would revolutionise the ADF's ability to engage threats at extended ranges. They are the first land-based, surface-to-surface missile system acquired under Army's future long-range strike capability.
"HIMARS will enable Army to strike land and maritime targets and is a key part of the Integrated Force's long-range strike capability directed in the National Defence Strategy," Mr Marles said.
"It delivers increased lethality and accurate firepower at unprecedented ranges, increasing Army's artillery range from 30-40 kilometres to approximately 500 kilometres."
The $1.6 billion acquisition includes support systems and associated munitions, such as the guided multiple launch rocket systems (GMLRS), which have a range of more than 70 kilometres.
Their missile fleet also includes the precision strike missile with a range of more than 500 kilometres.
Minister for Defence Industry Pat Conroy said it would give Army weapons with real reach and the tools to defend against land forces and ships at sea.
"Equally crucial will be the munitions and support systems that sit behind HIMARS - and that's why we're assembling GMLRS missiles in Australia this year, to reinforce robust domestic supply chains that we control," Mr Conroy said.
Fifteen gunners from Army's first HIMARS battery - 54 Siege Battery, 14 Regiment, Royal Australian Artillery - are undertaking HIMARS training at Fort Sill in Oklahoma.
The full suite of 42 HIMARS launchers are scheduled to be in Australia by the end of 2028. They will primarily be located at 10 Brigade, 14 Regiment, RAA in Edinburgh, South Australia.
Australia's HIMARS launchers will be showcased at this year's Exercise Talisman Sabre in a firepower demonstration.
