Gday Barefoot,
I presume those 1000 hours were earned as a swamp donkey? If so I was in exactly the same situation as you about three years ago. Some companies may (for whatever reason i dont know) raise a bit of a brow because you havent flown commercially in oz (maybe you have?) but keep persisting and you'll come right with a twin gig. I did years ago and the industry is alot healthier now.
Best of luck
