Adelaide City Guide

I have some time before my army enlistment in April and I'm thinking of going to Adelaide (in Australia) to stay with friends for about a week or two. What's the cheapest way of flying there and back? The exact departure date (anytime between Jan and mid-March) is flexible. I don't mind stopovers etc. Any help will be much appreciated!

Hi, I will be in Adelaide for 8 days. i have no firm plans on what to do there. My family have 2 options. 1) Self drive to Melbourne (the great ocean road) 2) go to Gold Coast (but i dont know what is the best & cheapest way to get there Can anyone suggest which will be a better option. i will be travelling with my family, all adults, in Feb. Thanks you for all your reply:) Kareen
