My reply will be completely useless. I live in WA in a Truck and sometimes a message / trip to the grocery store is a bit too far to do on foot. But the hassle of moving the truck... I used to have a bike bike when I was in Darwin and I just gave that up.
Perhaps I get a bit more confident operating the truck, I just fitted a reversing camera. BIG Difference there... or perhaps I just should put some svelte on these magnificent hiking legs of mine and my back pack...
