That's unfortunate to hear that you are struggling to obtain employment. I'm a practicing Professional Engineer in Australia and my take on the employment market for Engineers is that it’s quite buoyant, particularly in places like Gladstone and Perth, although December and January are usually the quieter months.
Engineering is one of those professions, like many other I suspect, where a lot of the practical aspects are imparted by mentors and peers or simply picked up along the way. I believe the best way for you to obtain these skills is to get into employment, whether with a consultancy or with a constructor.
I suggest you get in touch with the major consulting firms, like GHD, SKM, Hatch, Flour, Worley, Halliburton KBR, Maunsell, Bechtel and Connell Wagner, as well as the smaller firms in your area. If you are interested in construction, get in touch with some of the major contractors like Leighton, Thiess, John Holland, Clough, Multiplex, Baulderstone Hornibrook, United KG and Monadelphous. Check out the employment links at their websites and give their HR departments a call.
Are you prepared to move to a regional centre like Newcastle or interstate to places like Brisbane, Gladstone, Perth, Bunbury, Port Hedland or Karratha?
I think you just need to hit the Internet and the phones. If you are flexible you should find your way into employment and hopefully a rewarding career.
