Trailer rego charges- State versus Fed Interstate

Hi all,
Wondering what each state charges for a tri-axle semi-trailer (not prime mover) for 12months. I want to compare it against the Federal Interstate rego scheme charge.
I'm trying to prove a theory of mine on why most Qld trailers are registered with normal Qld trailer plates, rather than as part of the Federal Interstate Registration Scheme.
Thanks for your time.

Hoarder, one reason is that there isn't stamp duty on trailers in Queensland.

Hoarder, Here's what It cost per 1/4 to rego one in N.S.W. [

HOWEVER it will go up tomorrow 1/7/12.

ALSO We'll all feel so Much Better , ;DKnowing we'll all start paying the Fart Carbon tax

July 1 2012 (read in a cupla hours)
each axle on a trailer = $550
1 axle trailer = $550 up from 418
2 axle trailer = 1100 up from 836
3 axle trailer = 1650 up from 1419
4 axle trailer = 2200 up from 1892
etc etc

Short combination prime mover with 3 axles =$ 4327.00 Not B duble or Road Train

N U can probly count on each year add sum more dollar$
A Govt to waste money needs to collect it from sum where

I'm not sure if it's still applicable, but back when I ownned a bit of gear; Queensland had no third party insurance charges on trailers as it was covered with the prime mover. A bloke could find himself in a spot of bother towing a Queensland regoed trailer with a NSW regoed IS front bit.

Thanks for the replies to date. Generally the stamp duty remark combined with a couple of other ideas I have answers my initial question.
