Usually overseas tourists coming to Australia purely for recreation have no problems getting a visa to enter the country.
Most people simply obtain an electronic visa through their travel agent at the time they purchase their flight tickets.
Tourist visas are valid for 12 months and allow stays of 3 months at a time in Australia. Sometimes people want to extend their
stay and this is possible but has to be done via the Department of Immigration.
