In other countries they upgrade the airspace first before putting in RFFS.
In other countries they make the airport, so indirectly the operators, pay for the Fire Service. Imagine the landing fees if Ballina was paying for it.
That is they try and prevent the accident in the first place
Also, if the no. and type of movements or passengers dictate establishment of a RFFS, then so be it. The chance of a mid-air 5-10 miles away from the drome is not why they are there. They probably wouldn't even respond. Accidents in general airspace and at an airport are two different arguments.
