I would go for it.
When I went through NT (10+ years ago) there was plenty of work in the wet. The tourism dropped, but charter grew.
The Chief Pilot's of these companies are just blokes like you, a bit further down the path. If you're there, or within 24hrs of being there when they need someone, you'll get a job.
Having Cessna 200 time helped me get a job.
Good luck, pm if you want anything further.
