A $2.7 billion defence spend could help to boost recruitment to the forces. 

The Government's investing in new aircrafts, including two new Airbus A321 planes, in a lease-to-buy plan. 

Five Seahawk helicopters are also being bought. 

Air Force Chief Darryn Webb told Mike Hosking this will be appealing to potential new recruits. 

He says morale lifts when they have new equipment, and they're always able to get the most out them. 

Webb says the investment will benefit the forces well into the future – saying we always get more out of our assets compared to most countries, and predicts the aircraft will have around a 30-year service life.
