Making your tucker on the wallaby is an exercise in minimalist food preparation and cooking. Sure, you can take modern pre-prepared or freeze dried foods with you instead of the stuff the old-timers carried, but between you and me… that’s cheating. Taking a gas cooker or even an alcohol stove is cheating too. If the bushfire fire danger allows it, you use an open fire for your cooking. If it doesn’t then stay home or “cheat” and use a Jetboil and freeze dried slop-in-a-bag.
