This is so we can keep crowd control to a minimum - The time slot on your combination ticket is for your visit to SEA LIFE Sydney, this means this will need to be the first attraction you visit.
Please note that you will need to book a date or time for each attraction when purchasing an attraction pass.
To pre-book, please visit https://www.visitsealife.com/sydney/tickets-passes/ and scroll down to "Attraction Time-Slot Booking"
