After I entered Qld in 2001 my WA boat registration
expired so I went to Qld Transport and renewed it giving my home address as my vessel.
However I had taken the precaution of writing a "To whom it may concern" letter stating that the vessels log stated the vessel entered Qld waters about 2 months before and had remained therein during the intervening period. I took the log and the letter to a public signatory and had it witnessed.
This worked for the registration
but would not suffice for my drivers license
which required a visit to the local members office, a conversation with someone in the Ministers office (may have been the Minister) and a return visit. The address on my drivers license
id c/o "vessel name" c/o the Port Authority.
You must be careful of what you put in government
forms as in some jurisdictions knowingly including misinformation is perjury.
What you do with renewals is take a relevant form with a bar code on it and when you do the renewal change the postal address to where you want to collect their rejoinder. I generally use c/o PO for this. You have to keep track of what is renewable although I missed my drivers license and when I explained the circumstances they renewed it anyway even though it was a few months out of date. The down side of it is that if you get caught by a traffic camera
you may not be aware of the outstanding transgression until it has multiplied somewhat.
This happened to me when I crossed the Gateway Bridge. I wrote them a letter asserting my right to expunge the debt under the Currency Act and told them I would drop by a PO and pay the $3.85 in cash as was my right as a user of the Australian currency if they sent me an invoice but they just ignored it and threatened to suspend my drivers license. They don't appear to have done it yet though.
If I was you I would take someone with me when you lodge the transfer application and if they won't accept the truth of your residential circumstances and reject your application write up a stat declaration for yourself and your friend and take it to a magistrates court and for a small fee they will official-ize it.
Then if you end up in court you can show that you have done all you reasonably could to comply with the law. Be mindful that in Qld your speed boat license is attached to your drivers license and they are hooked up to computer systems in the cars and boats. With one thing and another Qld is turning into a bureaucratic hellhole for cruisers which is a pity as it has some of the more sublime places on the Australian coast,
