I think a cape buffalo is a great hunt to do.

More than just water buffalo to hunt in Oz, if one wants to. Pigs. Might be a few in buff country but good numbers nearby if one wants to arrange it. Other feral game such as donkeys, horses, camels too. Camels a bit further away. Scrub bulls are good sport. Banteng too, only place to hunt them. Many of these game will be in different places but all in the Top End.

Cape buffalo can have other species available but in big game areas, often plains game is more limited. A lot of hunters also organise a trip to a more productive plains game area.

Water buffalo can stand around if not hunted much, or very flighty if hunted a lot in the area where you are hunting.
