Propane is available but it just a bit more complicated to get. You have to drop the tank off at the special store and collect 2 days later. Not so good when you are in the middle of a cook-out and your flame dies. Most of the guys I know keep a second tank and rotate the tank thru as required.
The gas in the orange tanks which I am quite sure is Butane, or cooking gas as they call it here, is easy to get. Just a phone call away. You just need to get the adaptor. Problem with Butane is that is has a higher moisture content then propane and will rust out your burner much faster.
