Paddy William Macgillicuddy tells you had to save big money on the Sydney Trains Opal card.
Tip 1: only pay for 8 trips in a week. Every trip after that is free, so make lots of small, cheap trips at the beginning of the week and save.
Tip 2: spend less than an hour at your destination and return to your origin. You'll only pay the price of the cheapest single ticket.
Enjoy!
