Since 1788, the basis of Australian culture has been strongly influenced by Anglo-Celtic Western culture. Distinctive cultural features have also arisen from Australia's natural environment and Indigenous cultures. Since the mid-20th century, American popular culture has strongly influenced Australia, particularly through television and cinema. Other cultural influences come from neighbouring Asian countries, and through large-scale immigration from non-English-speaking nations.The food of Indigenous Australians was largely influenced by the area in which they lived. Most tribal groups subsisted on a simple hunter-gatherer diet, hunting native game and fish and collecting native plants and fruit. The general term for native Australian flora and fauna used as a source of food is bush tucker. The first settlers introduced British food to the continent, and much of that is now considered typical Australian food; the Sunday roast has become an enduring tradition for many Australians. Since the beginning of the 20th century, food in Australia has increasingly been influenced by immigrants to the nation, particularly from Southern European and Asian cultures. Although the country of origin is largely disputed between Australia and New Zealand, the meringue-based dessert pavlova has become an icon of Australian cuisine, popularly served on Christmas Day and usually garnished with fruit and cream. Australian wine is produced in 60 distinct production areas totalling about 160,000 hectares, mainly in the southern, cooler parts of the country. The wine regions in each of these states produce different wine varieties and styles that take advantage of local climates and soil types. In 1995, an Australian red wine, Penfolds Grange, won the Wine Spectator award for Wine of the Year, the first time a wine from outside France or California achieved this distinction. Tourism is an important industry for the Australian economy. In the financial year 2010/11, the tourism industry represented 2.5% of Australia's GDP at a value of approximately A$35 billion to the national economy. This is equivalent to tourism contributing $94.8 million a day to the Australian economy. Domestic tourism is a significant part of the tourism industry, and was responsible for 73% of the total direct tourism GDP. The 2010-11 financial year saw a record number of overseas arrivals in the financial year, with 5.9 million short-term visitor arrivals to Australia (or 588 extra visitors a day extra). Tourism employed 513,700 people in Australia in 2010-11, of which 43.7% of total tourism employed persons were part-time. Tourism also contributed 8.0% of Australia's total export earnings in 2010-11. Popular Australian destinations include the coastal cities of Sydney and Melbourne, as well as other high profile destinations including regional Queensland, the Gold Coast and the Great Barrier Reef, the world's largest reef. Uluru and the Australian outback are other popular locations, as is Tasmanian wilderness. The unique Australian wildlife is also another significant point of interest in the country's tourism.
