I'm not sure... Can you reprint the link? Does it go into more detail with Specs? Do you know what frequencies you need for your carrier? Who is your carrier?
If it is the same as the variant on the Microsoft US site, you would be good:
GSM (2G) quad-band is pretty much universal plug and play anywhere in the world
WCDMA (3G) is penta-band 850/900/1700/1900/2100 and I don't see anything outside of that listed for Aussie carriers
LTE (4G) is FD bands 1/2/3/4/5/7/8/12/17//20/28 and TD bands 38/40/41 and in Oz it looks like bands 1/3/5/7/8/28 are in use
But not being able to see it, I can't be sure.
