My V35 was trucked up from NSW to QLD cost was built into purchase price but on average I'd say around $300 - $500 depending on who you use. Car had 3 months NSW rego courtesy of car yard, so I drove it in QLD until it had about a week left, then went and got a safety certificate (most mechanics can do this, usual chk on tyres, leaks, rust etc...just roadworthy stuff) , took it to QLD transport and got new plates for it and that was it, easy.
