I biked about 5,000 km in Australia but now wish I did that walk too. I spent too much time in the Outback but also biked through some wine country, through Adelaide and then along the South Shore and up to Sydney so saw a lot of your beautiful country.
You’ve seen, and experienced, more of it than 99+% of humanity has. Australians are great travelers, but you’ve probably also seen more of Oz than most Aussies.
My brother teaches at ANU in Canberra so I very well might be back. He’s here in Canada getting married to a lady from Indonesia and they are going back to Canberra in a few weeks. I’ll show him the video, it will be something he’d enjoy.
I haven’t been to Sydney (although it looks nice in the video), but I have been to Cape Town and I don’t know if Sydney could top Cape Town in a “World’s most beautiful city” contest.
