Sydney Attractions Group has launched a new annual pass offering unlimited access to Sydney Aquarium and Sydney Wildlife World - 365 days of the year.

The passes, available for a limited time, are AUD$75 for adults and AUD$45 for children. "The Annual Pass makes great sense for families, couples and animal lovers, who can now make a trip to the Aquarium or Sydney Wildlife World as often as they like throughout the year," said Sydney Attractions Group CEO Kevin Bush.

"The habitats and exhibits at both our attractions are constantly evolving so we're very excited to be able to offer our guests a pass which lets them visit as often as they want to see the changes and become more involved with our animals."
