As with most of mySociety's other projects, TheyWorkForYou's underlying code is open source. A New Zealand developer adapted it to create TheyWorkForYou New Zealand, while in June 2008 OpenAustralia was launched by the OpenAustralia Foundation with the assistance of mySociety, putting the Register of Senators' and Members' Interests online for the first time ever in Australia. In April 2009, an Irish version of TheyWorkForYou was launched in beta form. Called KildareStreet, it contains Irish parliamentary data from January 2004 to the present day.
