TOURISM brings revenue of $343 million a year to the South West.
The region plays host to about 1.3 million visitors a year who spend, on average, $85 a day on services including accommodation, food and local travel.
The details are contained in the new Tourism Research Review compiled by the WA Tourism Commission.
According to the review, the top three leisure activities enjoyed by domestic visitors to the South West were going to the beach, visiting national parks and bushwalking, and eating out.
Of the total number of overnight visitor trips to the South Westin 1999, 1.28 million were made by domestic visitors and 51,000 by international visitors.
The growth in commercial interests in the South West is highlighted by statistics which show more than half of visitors to the region are there on business.
WA Tourism Commission southern area tourism development manager Mark Exeter said there was opportunity for the industry to increase its market share in the international marketplace.
