I previously hunted in Australia with Hunt Australia. The owner unfortunately passed away a few years ago so I was looking at different companies. I ran across Australian Outfitters. I looked at their webpage and found a link to the Northern Territory Police pdf for importing a firearm. I was thinking about a hunt with a 45-70 levergun, but looking at the form it seems to indicate you can import category H firearms for safari hunting. The same format shows Catagory H as pistols, including revolvers. Does anyone here have more info?
Here is the link to the website, the link to the application is about halfway down their homepage.
