Altahama is correct on the National Parks not being hunting areas.
There is a distinction between the National Parks and National Forest areas which are legal hunting areas here in Colorado.
Now, all big game hunting area here is divided into "game management units" which are usually smaller areas divided by ridgelines, roads and rivers etc.
I often dream of just being able to go out and hunt but here it is so structured as far as time constraints and competition with other hunters for the one elk or deer you are allowed on license.
Looks like hunting in Australia's NT is more like wide area hunting where many animals can be taken on a single hunt.
Looks wonderful!
