No-one will hire you for an overseas job unless you're already there.
For a first job, you can hope for but not really expect a "reliable" company to work for. If you have low hours, chances are they're gona take advantage of you for a while, whether its in N.T , Indonesia, Tanzania or wherever...
There definitely are jobs around though.
