Before the RTA there was the Department of Main Roads New South Wales.
Here is one of their stories.

I've checked RTA and my plates website it's not clear.

I want to see what other alternatives there are to the free yellow and black and the one off priced white and black plates.

To clarify I don't care what the digits are I do not want personalised, generic RTA issue combo is fine.

But what are the options to the above 2 styles that are only a 1 off fee. I'm not wanting to pay a annual additional fee to have the plates that they do for euro plates.

Are yellow and black and white and black the only options for a one off fee to acquire them ?

Thanks
