I would be looking into a Special Hardship Order, I'm not entirely sure whether the are applicable in your situation but it is worth a look. I had one in 2008 represented myself in court, wrote up all the affadavits and got them signed etc and got it no problem.
The problem is you have to plead guilty and cop the fine/be disqualified before you can apply for a SHO after you have been disqualified you have 21 days to submit your application. Once the application is submitted you're given a date to appear in court and you're allowed to drive up until that date. So effectively the disqualification gets put on hold. If you're well prepared you can organise everything so you don't have any date other than the court date were you can't drive.
Here is the pdf from QLD transport which tells you everything you will need etc.

The timeline for my application went something like this
Got caught for running red light on April 28 2007 while on a Good Behaviour Bond. (There is a story behind this but will leave it out)
Took it to court - Court date set for August 2007
Found out about the SHO the day of court and plead guilty, 28 days to pay the fine and cop the disqualification
Prepared my SHO application and affadavits, got them all signed by my boss and witnessed by a JP
Paid my fine and lodged the application on the same day. Was given a date for the hearing in Jan 2008
Went to court with all my documentation etc. Judge granted SHO in 5 mins.
This is probably the best result you can hope for.
