I've driven just over 20,000km, spending $4,500 on petrol. More importantly, I've walked over 600km on a dozen or more trails, spending five weeks - over a quarter of my holiday - on walking trails. I've been to many special places and met some cool people. Maybe I've learnt a thing or two as well. Australia is much vaster than I imagined, it is full of life, there doesn't seem to be any emptiness out there.
Thanks for all your comments and emails along the way, I'm glad you've enjoyed reading my blog as much as I have writing it.
