Australian Defence Force (ADF) personnel have been in Parkes this week conducting training and it's expected we'll still be seeing and hearing them around into next week too.

The training involves personnel responding to simulated warfare scenarios, largely on rural properties in the Parkes region.

Residents may have seen or heard military aircraft, unmanned aerial surveillance systems, vehicles and soldiers carrying weapons, and tactical equipment during the conduct of these training activities.

ADF sent C27 Spartans and a C-17 Globemaster III for an airdrop on Monday night, with one of the Spartans landing at the Parkes Airport.

The Globemaster - one of the Royal Australian Air Force's biggest planes - returned to base.

These activities are part of the regular training program and a representative of the ADF, Tristan Steventon, said residents should not be concerned if they hear or see these activities occurring.

"Local police and other authorities are aware of this training," he said.

"The purpose of these training activities is to provide personnel with realistic training environments and scenarios.

"Training such as this is conducted to ensure that the ADF has the highest level of capability to protect Australia's national interests and provide assistance in times of civil emergency."

Parts of the training will also involve the use of blank ammunition and some small and controlled demolition explosives.

Mr Steventon said noise disturbances will be minimised, wherever possible.

"The ADF thanks the public for their patience and cooperation while this essential training is being conducted," he said.

"The training poses no threat or danger to the public.

"Defence is unable to facilitate access or provide further information regarding this training in order to protect operational tactics, techniques and procedures."
