First, a warm Yank welcome!

I'm not sure what bullets you might have available to you down under, so I can't make a specific recommendation. I would, however, stay away from any hollowpoint designs. You'll lack penetration on those tough beasties you have. Stick with a tough softpoint.

You can ignore the barrel length difference. You'll not get much added velocity with the .45-70 simply because it has such a hich expansion ratio to start with. Perhaps 10 fps per inch is all. Use the loads as recommended by your manuals and tweak the loads by adjusting seating depth and crimp versus none.
