Someone said on the other thread it is only another name for Metho, same as used in Metho stoves.

Camping stores sell it but it is much cheaper (half the price) in places like Bunnings and I found it no different to the camping stores one.

I used it in my camping stove.  Metho can be put out with water in an emergency.

All hardware stores sell it and also some of the supermarkets. 

Trevor, like I said in the other thread for others info, I saw one of the round ones shown on your link being used outside by a tenter as a sit around fire, looked warm and inviting but not sure how much heat they were getting off it.
