The "Snowy River" rifle was a Martini-Henry from memory but there was a couple of movies it may have been a Winchester half tube mag. in .44/40 or .32/20 most Winchesters sold in Australia in those days had half tube magazines. Varmint calibres today in centrefire is mostly .223Rem and .22/250 then next popular for bigger game would be .243Win, .270Win,.30/30,.308Win,.30/06,.300WinMag, but you will find a large range of calibres available . The old .303British is still around but not as popular as it used to be. Australia does not make many firearms but we make Barrels,Powders (ADI-Hogdon),Brass (Bertram),Bullets (Woodleigh),also our custom gunsmiths make some of the best rifles in the world .The last all australia gun was a lever action shotgun based on a Winchester M1887 design but for 2 3/4" not many made.
