You Do NOT need 1000hrs to get hired or get work permits, however the more hours the better and still no promises that once you get hired that you will receive the permits, but the company that hires you will do its best to make sure that your work permits come thru.
Things are starting to look a little better at the moment with some companies receiving word that 2x300hr pilots have been approved by the government. If you get hired its most likely you will get work permits(eventually).
