Consider other towns in the area as Broome isn't the only place to start. Unfortunately your age will be a disadvantage in Broome. This is because majority of the work is scenic ops so F class endorsement on the drivers licence is asked by most of the operators. Min age for this is 21.
Also research the additional qualifications required by operators before you make the trip. ie First aid, Night vfr, F class drivers as mentioned above and if possible some 210 time to improve your chances.
Other towns to consider include Derby, Halls Creek, Kununurra, Port Hedland etc etc.
What ever way you go...best of luck
