Sydney - making a film - next steps

Then I would find a script. Now I could perhaps write one but having only lived in the city for a short while it would be too easy to fall into a kind of 'touristy type film' made by an outsider. One which is more firmly rooted in place will always be a better sell. I'd go online and try and find scripts, contact all the screenwriters courses advertised on line and see if I could circulate my details to the writers and specify the length of script needed. Then sit down and do a lot of reading. My criteria being

1. is this a good compelling story
2. is it a good story but not well told? Can the writer do rewrites?
3. is this feasible and realisable? You might need to find a Sydney based film producer or get someone to mentor you and would be prepared to answer questions. For example I know that films set on public transport in the UK are prohibitively expensive but that might not be the case in Australia.
