However one of the most important points was the introduction of airplanes to Australia, which has allowed people to travel over long distances in shorter times and at a more reasonable price (Barwick and Barwick, 2001; Jackson, 1989:14). .
Tourism sufficiently makes a contribution to Australian economy. First of all, tourism is one of Australia biggest economic activity. The total expenditure counted for approximately $ 47 from 1993 to 1994 (Skene, 1996: 5). This was 10.1 percent of GDP (Gross Domestic Product) (Richardson, 1995: 68). Tourism has activity made the scope of the Australian economy become larger and strengthened the gross economic- power. Jackson (1989:154) also explains that there are many indirectly and directly affected industries by the spending through tourism in the community. In addition, inbound tourism is Australia's biggest export earner. This inbound tourism has the same effects as exporting products (Dickman, 1989:154). Foreign tourists have to take overseas money along with them when they travel around Australia, thus Australia gain the foreign exchange earnings and contribution to the balance of payments (Dickman, 1989; Hall, 1995; Richardson, 1995: 68-69). Export income from tourism reached at about $17.1 billion, accounting for almost 11.2 % of all Australian Export earnings in 2000 (Tourism Satellite Account, http://www.atc.net.au/research.asp?art=2221, [12 Aug 2002]). Moreover, the tourism industry is a service industry offering a wide variety of jobs and creating new employment opportunities. Economists (in Barwick and Barwick, 2001: 22) state that in during the 1990s tourism was estimated to have provided approximately 440.000 jobs employing 8% of the work force. Next, tourists have to pay certain taxes, which are sometimes direct like rooms and occasionally indirect taxes such as fuel taxes (Dickman, 1989; Richardson, 1995: 87-89). Dickman (1989:164-165) clarifies that the improvement of tourism provides constant and much needed earnings for the government.
