This database (which can be searched here http://www.environment.gov.au/topics/heritage/publications-and-resources/australian-heritage-database) is a compilation of a set of lists: World Heritage List, National Heritage List, Commonwealth Heritage list, Register of the National Estate and Overseas Places of Historic Significance to Australia. While the search results returned are CC-licensed, it would be much easy to develop applications to work with this data if we could obtain access to the dataset(s) without having to resort to web scraping. Possibly applications include the generation of Wikipedia articles to better promote Australian heritage and encourage regional tourism.
