Oz Experience Oz Experience is a flexible touring network developed for travellers by travellers since 1995. The network encompasses travel all around Australia. You can hop on and off our 24-seat mini-buses (complete with DVD players) to discover the country for yourself.
The guides will tell you all about the flora and fauna, aboriginal culture, geology and points of interest. East Coast passes have activities included in the pass price: sea kayaking, an outback cattle station stop, Aboriginal cultural experience, zorbing, eco-guided treks, barefoot bowling, and learn to surf lessons. We suggest you get off the bus to spend more time hanging out at the beach or in the mountains for longer walks, go to Fraser Island or the Whitsunday Islands. But even if you don't get off we reckon you'd have a pretty good experience of what Australia's all about by the end of your journey. Push the boundaries, explore and discover, get on the ultimate ride with Oz Experience!
