Uhhh... A little too much too soon guys.
ttjarret: Could you tell us what your project actually is, so that our advice is grounded in something? And is it a solid circle, or a ring that you want? How perfectly circular does the circle have to be? And what's your budget?
First off, as far as I'm aware, you can get lasers into Australia, as long as they are not fully assembled handheld lasers. Might want to ask an actual Aussie about that, but I'm pretty sure that's how it is. Which means it shouldn't hinder you too much.
Secondly, green lasers appear brighter to our eyes than the other colours we have access to. This means it would take less power to acheive the desired effect and would probably be safer, but maybe you'd prefer red.
This: Circle lens kit for 12x30mm AixiZ modules, AixiZ as posted by Crazyk187 will work for producing the ring shape (as in the picture on the page) but will only screw onto an Aixiz module. It would be perfectly suited for use in combination with this: http://www.aixiz.com/store/product_info.php/cPath/59/products_id/310, although that is quite expensive and there are similar products available for much less. This: www.rayfoss.com has mixed reviews, but seemed pretty good when I got it, but that'll mean you shouldn't leave it on for too long at a time to prevent it overheating and would mean that you'd have to attach the diffraction grating manually, say, with some sort of adhesive. The benefit would be that it's green.
But, like I said, give us somet details on the project itsself and we'll be able to give more personalised advice - it might be a very common thing that you're trying with an easier solution.
EDIT: Maybe there's something I'm missing... qumefox, why wouldn't a 1m circle at a 1m distance be possible with the diffraction grating Crazyk187 posted?
