The OP has been in the industry for 6 years but no local experience. That is a big hindrance as far as job hunt is concerned. That said, it is worth spending a few $$$ on building your CV in the Aussie format. The CV is the first thing the recruiters will see and that needs to be really strong and attractive. Also, if you could use specific words in the CV that would help.

It's really surprising that you are not able to find a job being in NSW with 6 years experience

Maybe you are setting your eyes at high end jobs

Scrape the bottom of the barrel and take up even temporary or small duration jobs or contracts just to build your resume with local experience

Are you aware that the Australian CV is atleast 4/5 page long ?
Have you prepared th same as per Australian standards?

Cheers
