More than 600 New Zealand defence personnel are taking part in a warfighting exercise with Australia and the United States.
The NZDF has deployed two ships, four aircraft including two NH90 helicopters, 22 Light Armoured Vehicles and 23 other military vehicles for the exercise.
"Over the next three weeks, we will be training with key partners, Australia and the United States, in a challenging multi-national environment," said Colonel Glenn King, Senior National Officer (SNO) for the NZDF contingent.
A Tiger helicopter and a Bushmaster from the Australian Army, a US Marine Corps V22 Osprey and a M777 Howitzer are among the military hardware on display during the public open day being held simultaneously today in Darwin in the Northern Territory and Rockhampton, Queensland.
Colonel King says the exercise demonstrates Anzac co-operation, and reinforces the close defence partnership between Australia and New Zealand.
During the exercise, the NH90s will operate as part of the ADF's 16th Aviation Brigade will be given short-notice tasks to support troops on the ground and conduct air mobility operations.
Around 200 combat soldiers from the New Zealand Scots Squadron, Queen Alexandra's Mounted Rifles (QAMR Scots) will test their mettle in warfighting, including defending an urban area, while operating as part of the ADF's 7 Brigade.
And the Navy frigate Te Kaha will see "action" off Darwin in Northern Australia as part of the Opposing Force while the tanker Endeavour will help refuel the 21 ships.
The exercises will see almost 30,000 troops training in multiple locations in Australia and the US.
