MR2 Tow Hitch? Is there one available to buy in Aus?

Just wondering, is there an Aussie supplier who makes a good tow hitch for the SW20?
Here is a thread from the MR2OC, talking about such a thing:

... And here is the company, Curt, who make the hitches..

Apparently very good quality and they're rock solid. Obviously wouldn't be towing any sort of 'real' load. This is more of a thing for when I want to put the road bikes on the back and go for a trip to some place where there are some nice hills to ride up. Or maybe even tow a small trailer come rental property moving time, or when I want to pick up a Fridge/washer/you name it...

I'd like to support an Aussie company before I consider buying something like this overseas.

This would be awesome for towing a set of tools and wheels with slicks to the track. Unhitch the trailer, race for a day, hook the trailer back up and drive home.

I just found another pic that shows how it looks fitted, but it seems  like the safety chain hitch is behind the grille??
