My wife and I are in kl for 4 days, India 10 days and Doha a week. So is it best to carry Aussie dollars and buy the relevant currency until we run out and then use our band card or buy a traveled card. Where is it best to change money , at the airport as you leave australa or say whe you get to KL and buy Malaysian money with my Aussie dollars, either at the KL airport or at a KL bank.
