Sydney's shops vary from those with international cachet to Aboriginal art galleries, opal shops, craft bazaars, and weekend flea markets. If you're interested in buying genuine Australian products, look carefully at the labels. Stuffed koalas and didgeridoos made anywhere but in Australia are a standing joke.
Aboriginal art includes historically functional items, such as boomerangs, wooden bowls, and spears, as well as paintings and ceremonial implements that testify to a rich culture of legends and dreams. Although much of this artwork remains strongly traditional in essence, the tools and colors used in Western art have fired the imaginations of many Aboriginal artists. Works on canvas are now more common than works on bark. Much of the best work of Arnhem Land and the Central Desert Region (close to Darwin and Alice Springs, respectively) finds its way into Sydney galleries.
Australia has a virtual monopoly on the world's supply of opals. The least expensive of these fiery gemstones are triplets, which consist of a thin shaving of opal mounted on a plastic base and covered by a plastic, glass, or quartz crown. Doublets are a slice of mounted opal without the capping. The most expensive stones are solid opals, which cost anywhere from a few hundred dollars to a few thousand. You can pick up opals at souvenir shops all over the city, but if you want a valuable stone you should visit a specialist. Sydney is also a good hunting ground for other jewelry, from the quirky to the gloriously expensive.
