If you really want it, just go to your local hardware store and have them make up a quart of paint with the following formula:
Lamp Black: 0 5 0 (meaning that it has 0 ounces, 5/48ths of an ounce, and 0/96ths of an ounce of lamp black)
Thalo Green 0 1 0
Now, if the Aussies use a different system, say metrics, then we'll have to convert the formula. Should be relatively simple. Just find out how the Aussies mix paint. Do they add pigment in milliliters (ml)?
You would also need to find if the Aussies use the same color pigments ... I think they do.
All of that said, personally, I don't know why you would want it. I tried it and it threw all of my color balance off to too much blue.
