Information (in English) is divided into broad areas, one covers statistical trends for inbound and outbound tourism, one deals with ‘insights’ in the form of short posts and longer reports, one covers ‘studies’ on topics such as the state of overseas travel and a survey of the future overseas travel sentiment among Japanese travellers in light of the pandemic, and finally a category for ‘publications’ including on ‘International Green Tourism’. 

Plenty of evidence regarding the economic importance of tourism is made available, along with a guide that describes the various agencies in Australia that release tourism statistics.
