About $70 for the roadworthy (yep, you have to get one, even for a new car) and then your rego/third party. So for 12 months around $700 I think, I just did this a few weeks ago on a new triton going from WA - QLD. But then you'll get a refund on the un-used NSW rego.
PS, the Triton is very good value for the GLX at around $29990 atm, imo. I'm very happy with mine.
