Australia's commitment to Shanghai World Expo will be the nation's largest ever to an Expo, and is a reflection of the importance placed on the relationship with China, Commissioner General for Australia and Executive Director, Shanghai World Expo 2010, Lyndall Sachs said on Monday.

Sachs said the government has invested 83 million Australian dollars ($76 million) in projects for the Expo.

Construction and fit out of the distinctive weathering steel-clad Australian pavilion is moving quickly: it is set to be the first of the international pavilions to be completed.

The Australian federal and state governments have sought to leverage the opportunities to strengthen cultural, educational, trade and economic relationships that Shanghai World Expo presents.

The Shanghai World Expo, which is the largest Expo ever held, will attract over 70 million visitors from around the world who will come to see exhibitions from over 192 countries and 49 international organizations.

From May 1 to October 31 2010, Australia's visually striking national pavilion will showcase Australian innovation, creativity and achievement to some 7 million visitors mostly from China - an average of 38,000 people on each of the 184 days of the Expo.
