I am meeting my son (who is currently in Australia) and spending time with him in Perth, Melbourne and Sydney during the month of December. Then I am off to New Zealand to visit friends. On my return to Oz, I intend to travel up the East Coast from Brisbane to Cairns, taking in Fraser Island and the Whitsundays trips. I am a young 54 year old female and will be on my own for this. I would appreciate any useful info for the older traveller as I would imagine most people will be young backpackers.
