Sydney's shops range from those carrying high-class international brand names such as Tiffany's and Louis Vuitton to one-of-a-kind Aboriginal art galleries, plus opal shops, crafts galleries, 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 have become a standing joke. Business hours are usually about 9 or 10 to 6 on weekdays; Thursday is a later night with stores open until 9. Shops are open Saturday 9-5 and Sunday 11-5, roughly. The sticker price includes the new Goods and Services Tax (GST).
