Thanks for the Kudos guys; the first picture was taken during a hunt last year. After spying the bull from a distance I placed myself in an ambush positioned as the bull gradually feed towards me. Out of the blue he glanced in my direction and spotted me from about 80 meters. I was confident that was the last I would see of him as most of the bulls we encountered bolted once spooked. As expected the bull bolted though after traveling about 50 meters he about faced and commenced to march in my direction, not having any suitable trees to climb nor rifle backup I wondered why the hell I now found myself in this position. Reaching approx. 20 meters he turned and bolted once again only to turn and pace in my direction yet again.
By this stage I was at my wits end, the whole time the buff had moved in a semi circle from my right when I first encountered him to my extreme left, obviously attempting gain my scent, it was here were a shot opportunity finally presented itself. As the beast quartered away I was able to place an arrow in the short rib, the bull made a quick dash only to travel 40 odd meters and expire in less than a minute. The whole episode lasted 12 minutes and was captured on video.

There are no restrictions as to how many buffalo are taken or when they are hunted, also neither tag nor license fees. Though the hurdle for self guided individuals is gaining access to hunting locations. Alternatively there are many guides located throughout NT that offer guided buffalo hunting.
Are you planning a trip down under IronBuck? If so we have great bowhunting opportunities for many species.
Great to hear you have had good success with your Gold Tips they are a popular arrow amongst many hunters here in Oz.
Cheers.
Here's some more pics enjoy!
