You can spend half a day exploring North Head National Park. From Shelly Beach to Q Station there are a lot of Australian plants and animals to see.
Close to the Fairfax Lookout you can find Bella Vista Cafe. It is a lovely place to have a cup of coffee and enjoy the beautiful view.
You can take the 136 bus there or it is a 50 minute walk from school. Go with your classmates to extend your English speaking time.
