I am going to Australia for the first time (and likely only time because it is so far) for 4 weeks. I already have booked a week long stay in Manly (Sidney) a weekend in Blue Mountains, 5 days in Red Centre (which includes a 3 day camping tour to Uluru, etc) and not yet booked a week in Cairns-Port Douglas. With my remaining time should I go to Adelaide or Melbourne or both? Or should I skip those places and go to the Gold Coast?
Any advice would be greatly appreciated. I feel like I'm spending a lifetime on the internet researching for this trip - which is both exciting and overwhelming at the same time!
By the way, I am a mid 30's female from Canada travelling solo. I won't have a car but rely on public transit everywhere or a tour. Due to my ambitious itinerary I will be flying from city to city.
