great report so far Mr Cob! Welcome to down under I am off on a ride for 3 weeks towards Melbourne then off to the flinders ranges in late October, I hope we cross paths!
When it comes to heating here, as you were discussing prices of the hamburger being expensive so is power/electrcity, we down here are not subsidised for power at all and a quaterly bill in a normal house now can be anywhere upwards of $700 so putting on a jumper is often the cheapest way to heat!
I have now purchased 3 bikes from Roland at Better Bikes over the years and a cleaner, better run shop in Sydney you will not find, they know their second hand bikes here!
Need any help or parts PM me and I will help you guys out, that legend Jock will look after you well, look after him as well, Enjoy the ride!
