It has been a bucket list trip for Dad (the Ghan) since Mum died so we are making it happen. And Jon (DH) loves deserts so he will like Northern Territory and Western Australia.
It is the change of temperatures that makes it tricky. The only dressy occasions really will be the dinners on the train - I think I could wear shorts and a teeshirt or a casual dress and denim jacket everywhere else. Probably with flip flops or birkenstocks - it's just not a dressy part of the world!!
I think I could do
Hiking shoes, running shoes, flipflops, sandals
Hiking shoes, TEVA walking sandals, flip flops, dressy sneakers
The hiking shoes will be good for rocky trails and if I am going through water. I love my Merrells and they are so good on uneven ground (much better than running shoes). I don't think I will be doing much city walking, but potentially a couple of times in Adelaide and one day in Darwin.
I also need something to travel on the plane in.
I will be washing clothes along the way - I don't mind doing this at all. So I would rather have my footwear sorted and repeat and wash clothes!!
