Don't forget also the drones. The 7.7m was only for a trial.
They are  going to be tested mid july during 2 exercises.

The Army plans to evaluate the potential of the systems next month as part of two exercises: Hamel and Talisman Sabre.
"The evaluation will focus on the employment considerations of the [drones] in contemporary land combat and surveillance units," a spokesperson said.
"It will review the enhanced capability the technology provides, as well as the systems, structures and processes required to realise the capabilities’ maximum potential."
Both systems are used for surveillance and reconnaissance and will help units to increase their awareness and protection, the spokesperson said.
"Traditionally, the Army would request the support of larger aerial surveillance systems, such as the Shadow; or, employ less technical methods of surveillance and reconnaissance to support battlefield awareness requirements.
"The ability to provide [the Wasp and Black Hornet] to combat units provides tactical commanders a more responsive information collection asset.
"It also allows operators to remain at a safe distance from observed target areas, enhancing force protection in an increasingly lethal battle space."

If the ADF decides to deploy the UAVs, it won't be a 7M contract.
