Not so much a deal, but a nifty trick to get cheap tickets to SEA LIFE Sydney Aquarium. The general admission price on the official website is $51 for an adult and $38 for a child. If you book via trip.com, it’s only $29.50 for an adult and $28 for a child.
The process was easy too, you book via trip, and they send you a confirmation with QR codes for each ticket. I went today and they just scanned the QR code from the email at the door.
