After taking some time off from this issue, I've considered the next logical step to be contacting the relevant government departments in charge of the timezone legislation in each state. As a Queenslander I will start with the Queensland Attorney-General, as the timezone legislation falls under his responsibility. I honestly believe that the only argument for the status quo on this issue is that it's been this way for a long time. I have previously presented many good arguments as to why it needs to be updated to reflect what is widely used amongst government and private organisations across the country, and what is presented by the federal government on this page http://australia.gov.au/about-australia/our-country/time Hopefully, with responses from the relevant state departments, this issue can be resolved and put to bed.
