Climb the Sydney Harbour Bridge
Where: Sydney

It’s not every day you get to scale the world’s largest steel arch bridge. Totalling 1,149m (3,769ft) high, it’s a long way down from the top of the Sydney Harbour Bridge. But the 360-degree views of the sparkling harbour, city skyline and Blue Mountains are well worth the goosebumps. While you ascend to the summit in your harness, you’ll hear fascinating tales of the bridge and harbour’s rich history.

Once you’re kitted out with a harness, helmet and wetsuit, prepare to wade, jump and abseil your way through the temperate rainforest before the big finale: descending 30m (98ft) down the thundering Empress Falls.

Dive with great white sharks
Where: Port Lincoln in the Eyre Peninsula

Coming face to face with a great white shark is an incomparable adrenaline rush. In the waters off the southern tip of South Australia's Eyre Peninsula, you can climb into a cage where nothing stands between you and a great white but steel mesh. You'll be suspended just below the surface, breathing through a 'hookah' as you scan the ocean for the first glimpses of a shark – sometimes almost 6m (19.5 ft) long.

The Gold Coast is famous for its high-rise towers and sparkling blue stretch of coastline, and you'll get a great view of them both from the top of the city’s tallest building. At 270m (886ft) high, the SkyPoint Climb to the summit of the Q1 Resort building is Australia’s highest external building climb. If the stairs to the top don’t take your breath away, the view certainly will.

Where: Denmark, about a 4.5-hour drive from Perth

The trees of southern Western Australia are among the tallest in the world, soaring up to 75m (246ft) high and 20m (65ft) wide. These mind-boggling trunks were once part of the supercontinent Gondwana and hold more than 65 million years’ worth of history. Feel chills down your spine as you walk between them along the Tree Top Walk’s suspended walkway. Looking down from the highest point – 40m (132ft) above the ground – you’ll see why they call this place the Valley of the Giants.
