Hi mesmer,
Have you actually applied for a job online or checking the online job websites and haven't see a job that you maybe qualified for or that interests you?
In briefly reviewing your resume, I saw three things that stood out. The first one is in regards to your email and website with both end in "uk". I think in anyone reviewing your resume might be confused of where you are located. Even though you do have an address and a phone number in Australia. The "uk" does stand out. People might think you only live temporarily in Australia? The second item is when checking out your website and the "contact me" link, you still show to have a UK address and mobile phone number. Just a suggestion that you might want to consider updating to your Australian contact information. Unless you have still have a business in UK that requires you to keep the UK contact information?
The third item is in regards to your resume. It does not have a "career objective" of what type of job you are looking for. An example of an Australian CV template can be found at :

There are other websites with more Australian CV templates for you to choose from. Another website with some useful information:
Australia: Applying for jobs | Prospects.ac.uk
Not all jobs are posted in seek.com.au , mycareer.com.au But you might want to check out the websites of companies near your area. Most companies do have a careers section link with job openings too. In addition, you mention that you used to teach basic I.T. for people with alcohol, narcotics,etc. issues. Have you looked at these type of facilities that treat these people if there is some type of career training that might require a teacher for I.T.?
Some career counselors that I've seen on tv here in the US state that sometimes you have to be proactive in finding that job. That means even if there is no job posting, you can start sending your resume to companies that you feel your experience would be a fit. Or join a professional network such as
World's Largest Professional Network | LinkedIn This website also has job postings that you may not see in seek or mycareer.
