I've just gone through the dramas of doing this too.
I put $0 on the plate transfer form and sent it to state revenue, 3 weeks later get a letter back with the same form saying I have to put an amount in it, So I sent it back changing the $0 to $1 and wrote on the form with big letters "Happy Now!"
They've just sent back my form today with a grand total Stamp Duty Fee of $0.00
it says on the back $2 transfer fee waived, hahaha.
so make sure you put $1 as the fee or they send it back to you.
now I have to go to DPI and get my plates back and pay their stupid fee too, $60ish I think
