The black bags contain my empty panniers. I put the contents of the panniers into a duffel bag which worked really well. The duffel bag was easy to carry.
Another thing I did this time, different from previous times, was to use a light, open-topped, tote bag for one of my carry-ons. In it, I had my handlebar bag, and a few other items. That was incredibly easy to carry and very convenient.
My story and photos are going up in my Australian Tour thread ... which links to my website.
