Last year I was looking at doing this for a deal in Mackay, the deal didn't get over the line but I spoke to a company called Paradise Outdoor Advertising.
I think they only operate in QLD but Peter was very helpful.
Here are their contact details:

Cheers. I’ll reach out and see how we go. Happy to provide feedback to the forum
@dashsiva that would be great.
