Aussie looking for advice on investing here or in Aus

[TylerDunne]

Hi,

I'm most likely going to be long term in Japan, and am now looking into investing for retirement. I'm 41 so I've left it a bit late but hopefully not fatally so. As I'm a complete beginner at all this I would appreciate any advice people can give, but especially things pertaining to Australia, for example if I should pay into superannuation, taxes I might have to pay regarding investing, whether I should or shouldn't be splitting my money between here and there. Any advice above "You use money to buy things" will most likely be helpful and appreciated.

Thanks!
