Quoting from OpenAustralia's news item, Read the Register of Senators' Interests here,
Today is a big milestone. We are the first website to make the Register of Senators' Interests available online. This important public document until now has only been available to the small number of people who were able to visit the office in Canberra where the documents are held. In the Register each Senator declares information of financial interests, stocks and shares held, gifts received over a certain value, and memberships of Clubs and Associations.
The site is also seeking access to a bulk scanner to help them make the register for the House of Representatives' Members publicly available online.
Contact them if you can help.
