206dvr,
call the following if you like. It can't hurt.
The Helicopter Group
Heli-Serv
Professional Helicopter Services
(all contracted on fires with 206's and in Melbourne)
Minimums for Vic fires are: 1500TT, 100 on type, fire ex, complete online DSE Wildfire Awareness course. At least that is what it used to be I think. The operators will know.
