I am tentatively planning on cycling from Perth to Sydney from early July to mid September in 2025. I am 63, now retired, cycled cross country in 2016. (You can see my blog at CGOAB, Doc Bolby Rides across USA if you want to know all about me

I have gotten a friend interested in helping by driving a one-way vehicle rental from Perth to Sydney to haul, water, camping gear, food, etc. so one can ride very light and camp out in relative comfort.
Route will be almost entirely on paved roads and cover approximately 5200 km over 9-10 weeks so average distance per day will be a comfortable 90Km with lower mileage for the first week. Reason for this time is one can expect tailwinds out of the west, but it will be cold. Several rest days planned approximately 1-2 every week.

If you join I would only ask that you contribute to sharing common costs: rental vehicle, gas, whatever food we cook/consume together as a group.
