Opal Reviews 2

Ridiculous system without clear price structure. You're told there us a limit how much you can get charged yet then when you get back to the airport they make you either top up 20 Australiam $ or via the App $10. Once you've tortured your roaming plan for the app and pay, you have to wait another 15 minutes minimum, which you are not told beforehand. Furthermore you're left in the dark in the App when you're topped up in the system. Huge stress when you're trying to get to your international flight. Makes me think the principles of working of Utopia were applied in designing this.

Looks cool. Works great.
