I have to differ to the above comments at least in respect to my own state- 357 and 44 mag carbine quite popular in QLD, 44-40 not uncommon too. Lots of use in open forest, grassland, woodland and rainforest( of course). If you check gun classifieds there are always plenty going for sale. Some are cowboy action guns but a lot the seller specifies prior hunting use. Plenty of brands of hunting ammo for 357 and 44mag on shelves too, not an indication of obscure calibres.
