If you study or work at The Australian National University (ANU) you know how fortunate you are to spend your days on Australia's most awesome university campus. Set on 145 hectares of parkland in the middle of Australia's capital city Canberra, our campus is surrounded by natural bushland, complemented by award-winning architecture, and houses state-of-the-art research and teaching facilities. All this is just a short stroll from the heart of a vibrant, cosmopolitan city centre. Use our special "Look Around ANU" technology to pretend you're here with us. Immerse yourself in some of our most beautiful, significant and beloved places and spaces. It's almost as good as being here... but not quite. We'd still love you to come and visit us for real.
