Texas? For God's sake why? lol
Flag's is right. Everything you might want to hunt in Texas has a price tag on it. Many choose to buy into a hunting lease. People who can't afford that tend to hunt from the road.
If it has to be Texas. There is some really good fishing and traveling again like Flag's said, to Colorado or New Mexico is not a bad idea.
Did you hunt hogs with dogs in the North territories? The dogs here as you may know are a little different. Some of the hog hunters here have connections in Oz, and maybe you could hook up with a hunting crew to get you going once you move here.
Good luck!
