Indoor Activities for Kids and Families in Sydney

While there’s plenty of fun to be had outdoors in Sydney, there are a lot of fun indoor activities for kids and families too.

These are just a few of our favourite indoor activities for families visiting Sydney, whether you’re looking to escape the elements or just enjoy some indoor time together.

An unmissable indoor activity in Sydney, SEA LIFE Sydney Aquarium is a fun day out for all ages.

Wander through the aquarium at your own pace, stopping by a favourite exhibit for a while—the tunnel walkways with all kinds of water life swimming around you are a popular feature. If you and the kids are really keen, you can even try diving with sharks!

SEA LIFE Sydney Aquarium sits on Darling Harbour in the heart of the city. You’ll be able to step out and wander through Sydney to find a delicious lunch or dinner.

You can make it even easier on yourself by staying nearby. The family-friendly Novotel Sydney on Darling Harbour is just across the water from SEA LIFE Sydney and is home to some of the best dining in Sydney at The Ternary.

With a focus on arts, science, innovation, and design, the Powerhouse Museum is a must-visit attraction in Sydney for families who love learning about all things  science and innovation.
