Next day, I'm ready for some serious art. Sydney's 17th Biennale, at locations throughout the city, is an event worth crossing continents for. I take the free ferry to Cockatoo Island — a former prison, shipyard and the largest island in Sydney harbour, for a real artistic feast. Casbah by French Algerian artist Kader Attia — exhibited in a cavernous hangar, where you walk on the shanty town's corrugated roofs — symbolising first world oppression — and Ten Thousand Waves, a nine screen video installation by black British filmmaker Isaac Julien, are the highlights.
