Good price for a brand new last gen top of the line Windows 8 phone. It has practically the same specs (par the weight difference) to that of the higher priced Lumia 925!
Apparently it comes with 24 months warranty however I'm not sure if this is manufacturers warranty or if it's the sellers own warranty. Having said that, the item is based in Sydney.
"All online purchases on mobile phones are comes with standard 24 months store warranty (conditions applied for these extended warranty programed). Whilst 12 months warranty are covered for all accessories (Phone Accessories, including battery, usb cable, wall charger & earphones are comes with standard 6 months warranty.)"
I think it is seller's own warranty.
That being said I don't think Nokia warranty is that good either. I had really bad issues with Nokia warranty with my Lumia 925, I've sent it via Dick Smith because that is where I bought it. The service center lost my phone and couldn't track it for a whole week. Of course, it's just my experience, so I may have been unlucky, but they couldn't track it even with tracking number and everything.
