Australia is live on Travelog with two cities: Sydney, anchored by the Sydney Opera House, UNESCO World Heritage-listed in 2007 as one of the 20th century's great architectural works, and Melbourne, anchored by the Royal Exhibition Building and Carlton Gardens, UNESCO-listed in 2004 as the first Australian building ever inscribed on the World Heritage List.
Sydney and Melbourne each carry a direct UNESCO World Heritage listing, one of only a handful of country pairings in Travelog where both cities clear that bar independently, covered in full below.
