A little of topic, but are these 'cookers' allowed on Fraser Island (beach camping)
Below is from the NPSR web-site
A fully enclosed cooking or heating appliance, preferably using gas or fuel, can be used at all camping areas unless a total fire ban is in place.
•The appliance must use only manufactured fuel.
•It must be used for cooking and/or heating only.
•It must be 20cm off the ground.
•Manufactured fuel does not include timber or wood.
•Appliances that are not fully self-contained, such as braziers, are not permitted.
•All appliances, materials and fuels (e.g. heat beads) must be removed from the national park on departure.
