I think that you get one vehicle and a boat on concession.
My Motorhome is my vehicle and I nominated it for the concession. I get $257.45 credit off my yearly rego for the MH. I no longer have the boat so don't know that figure.
This is in Qld. I paid it online today so the figure is correct at this point in time for my motorhome which is a heavy vehicle between 4.5 tonnes and 16 tonnes.
Not sure on the figures for under 4.5 tonnes but you can claim one vehicle as a concession so obviously the choice is yours.
Same in Tassie - 1 vehicle concession per pensioner only. It is based on the number of cyclinders there, the MH cost the same as our old 4WD to register.

The wife owns the car and I own the motorhome. Get concession on both that way. Didn't even need to pay stamp duty on the transfer of car from my name to wife. I still pay both bills but now less.
QUEENSLAND - I have the car (solely owned by me) rego'd in my name and the van (joint owned by both of us) in my wife's name, we're both pensioners, BUT, the stingy Qld. Govt only allows ONE vehicle rego concession per COUPLE - as the car rego is the dearest, that's the one we get the concession on, the van we pay full fees for. Strangely, I can have one vehicle concession AND one boat concession, but not two vehicles. Maybe if I get the van registered as a boat !!!
