Scale the heights
Take in a 360-degree view of Sydney from the top of the Sydney Harbour Bridge with the award-winning BridgeClimb. Your team will walk along catwalks, climbing over and under the famous bridge - reaching the summit, where you'll have the entire Sydney Harbour at your feet. Take a team photograph at the top, then toast your climb with drinks and canapés served in your exclusive space, while photos of your climb are projected onto plasma screens. Climbs can cater for large groups, recently hosting a corporate climb for more than 2000 people.

Drama queen
Once you've seen it from above, see one of the world's most iconic venues on a private tour of the Sydney Opera House. Your team will have access to areas normally reserved for performers. Stand on the world-famous Concert Hall stage, take up the conductor's baton in the orchestra pit, or sneak a peek inside the stars' dressing rooms. Follow with a performance at one of the world's most celebrated performing arts centres, and a pre- or post-show dinner at the Bennelong restaurant. Backstage tours accommodate a maximum of 12 guests.

Pièce de résistance
Imagine Melbourne's icons and attractions swathed in monumental works of art created by your team. Big Stick Adventures 'Paint the City' programme sees teams create giant artworks which are then displayed in attention-grabbing spaces, such as wrapped around Australia's tallest building, Eureka Tower; covering the surface of the Melbourne Cricket Ground; hung from a helicopter and flown over the city; spread across Federation Square; or carried by boats down the Yarra River. You may even make the news. Suitable for large groups 50-100 people.

Go underground
In the opal mining town of Coober Pedy, South Australia, around half the residents live underground in 'dugouts' - built to avoid the often scorching heat. The Desert Cave Hotel in South Australia is the world's only underground hotel, and offers meeting facilities for up to 180 delegates, along with underground accommodation, underground shops and galleries, and an underground bar and gaming room. The hotel arranges specialised group tours of the South Australian outback, including fossicking for your own gemstones.

Swim with sharks
Come face-to-face with a real Great White Shark in South Australia's Port Lincoln, the home of shark diving in Australia. No diving experience is required, and up to eight people can enter the cage at a time. Your team-mates will be lowered into the deep blue to meet the ocean's top predator. Don't like the idea of being in a cage? Adventure Bay Charters has an 'Aquasub' underwater viewing platform where you can view the fierce creatures while staying dry. Private boat charters can cater for up to 27 guests.
