If it makes you feel any better, everyone who works in the industry has had their first job at one point or another, so it is achievable, sometimes it just takes time.
You'll find this industry is either flood or famine. There’s no jobs in sight for 12 months, then all of a sudden you have 3 job offers within a week.
As others have said, don’t restrict yourself to Darwin. Networking will be 50% of it, because someone you’ll meet will know of someone who’s just about to throw the towel in and that’s your opportunity to be ready.
My biggest piece of advice though, is DON’T under any circumstances, go and become an instructor if you only want to do it for the hours. You’ll be doing yourself and your potential students a disservice.
It'll happen, just be ready.
