Hi,
Just letting you know I’ve added Sydney to my supported GTFS feeds
It’s a small app that I’ve created for personal use for me, my wife and a few of our friends from Brisbane, but now I need to find some people from Sydney to use it ! 
No need to install anything on your phone, you just need to point your browser to the following urls:
Brisbane - http://catchit.duckdns.org
Sydney – http://catchitnsw.duckdns.org
Melbourne (gtfs realtime not available) – http://catchitvic.duckdns.org
Cheers
