I'm thinking about getting a 6 metre-ish boat and would like to tow it across state boundaries to go to warmer places for winter. As far as I can see all states impose a supposed max towing width of 2.5m. But some appear to be flexible with over size dimensions and some do not if the beam is over 2.5m e.g in Vic with transom lights, oversize sign etc up to 3+m is OK but doesnt appear Qld or SA has this flexibility.

Towable Oz built boats seem to stick to the 2.5m max width but towable USA built boats do not ie they are around 2.6+m I there seems to be a disconnect. How do owners of boats built in USA that are supposedly trailerable but over 2.5M wide get away with this?

I would like to avoid spending hours on the phone with each of the state road authorities to clarify and I cant find any info on the net that answers this.

You can get overwidth permits but is a pain in the is West Australian criteria.
Vehicles operating on permits issued on the basis of this policy will require
“Oversize” signs front and rear, to have their headlights on in the dipped
position, to have flags on the extremities (450mm square) and to have an
amber rotating flashing light. Night time travel will not be permitted.
Would have thought buying an Australian made boat that complies would be a tad easier. There are also rules that dont allow taking into built up areas, So even passing through a town and wanting to do some shopping becomes a hassle. On some of the naroww roads up this way when a road train comes at you it will be you that needs to drop off the road, dangerous and possible damage..
If a problem occurs with trailer not much chance of retrieval as over width..Most clubs dont have the facility to do that type of work.
All in all not a good idea.

Yep, 2.5m is the max after that you have to go to oversize.

I have seen quite a few oversize boats behind cruisers and effies in the last few weeks between Agnes Water and Bundaberg.
They would have been 7m+ and all had oversize signs and rotating amber lights. They were about 1m wider than the traffic lane. 1 was a charter dive boat on a quad wheel trailer, 1 was a big shark cat with twin 300hp outboards that wasn't much smaller than the dive boat and the rest were just big custom plate boats.

So can be done in Qld but it got a bit hairy when a semi wanted to come past with the roads being as bit narrow and both had to drop off onto the bad shoulder to pass.

As already described in the first reply,
also you will have to nominate which roads you will be using (all of them!).
