Home outdoor cooking apparatus for high heat cooking (wok, stir fry)

I don't know what's available in Australia, but in the US they market high-output outdoor burners for deep-frying turkeys. This one is marketed as 200,000 BTU, twice the output of the ones often used in Chinese restaurants. (This $1,000 restaurant wok is marketed as 90,000 BTU.)

Most outdoor turkey fryers are marketed as 60,000 BTU, which will probably work reasonably well. They are decidedly not to be used indoors; YouTube has many videos of people setting their houses on fire.

Getting one in Australia may be a challenge, but they're very common in the US, and many kitchen stores and (oddly) hardware stores. I imagine you could have one shipped, though I'd verify that your propane tanks are compatible.

I'm Australian as well and almost wondering if being a professional chef you're discounting some wok burners that have a lower heat output than professional units but work well for home cooking. I use the side burner on a gas BBQ and just checked and it's rated for 15,000 BTU. I use it along with a traditional Chinese wok that's made of fairly thin cast iron and get the following sort of results:

• For shallow / deep frying I leave it turned up for a couple of minutes to warm the oil (which I guess in a professional environment isn't desirable) but after that leave it set at about 1/3 and it keeps the oil at around 180C.

• For quickly searing I leave it on high temperature lightly oiled and after a few minutes add meat and while I've never measured the temperature I guess it's around 250C or more and it takes peanut oil past the smoke point.

If you're open to waiting a few minutes then apart from getting a gas BBQ with a side-burner there's also a lot of things available here quite cheaply like a Primus Wok Cooker - Double Burner. You could place that on top of one the modular cabinets made for outdoor cooking and put the gas bottle inside.
