Duty-free allowance

I need to clarify some doubts. I have never traveled internationally and I will be going to Perth soon. So, I need to know am I allowed to purchase duty free liquors in Perth as well as in Malaysia (that means 1 litre each from the airports) during my return?

    Thank you.

Errr....if I recall correctly,you can only bring in 1 litre of booze into the country duty free, regardless where you bought the booze. If I could get 1 litre duty free from everywhere, wahliao....untunglah saya!

You can bring 1 litre of alchole and 1 cartoon(10s) ciggerete.And if you are a muslim citizen of malaysia you are not allowed to bring any alcohol.Anyway they dont check the amount of alcohol so you can get a 2 Liter bottle.Hope they wont be dificult with you.Its the number of bottle they count.
