One problem is that the RFS/CFA are a volunteer organisation and may only be able to do hazard reduction at weekends. This could mean a need for full time hazard reduction teams.
Would aircrew be full time or volunteer?
Easy fix. Pay the local Fireries to do it during the week.
Some are calling this a National Emergency.
So hazard reduction burns need to be done WHENEVER the conditions are suitable. Not when it suits some volunteers. I would think the "token amount" it would cost to pay some professional Fire Men some overtime to conduct controlled burns would be far cheaper then the few Billion this summer is going to cost.
