Sydney is a traction city that roams the deserts of Australia. It was set to appear in the unreleased comic The Haunted Sky, where aviators from across the globe will travel to it in order to participate in an airship race.

It is decribed as having the Sydney Opera House balanced on the top tier at a 'jaunty angle'. Another interesting feature with Sydney (and aparently other Austrialian land-traction cities) is a collection of giants corks hanging by chains of the edges of tiers, alledgedly to swat off anti-tractionist airships that reside in the Blue Mountains.
