All went well with the trip down, and I've reached Sydney now. There's still a few hours' drive into the place where we're staying, but otherwise have reached the destination. I will also be trying to get to a Latin Mass during WYD, so that still needs a bit of organizing.
Most of the newspapers I've seen have a positive message about WYD so far, so hopefully that's a good sign of the future.
Only 3 days to go now!
