Voter action group surveys:
Reignite Democracy Australia: QLD Candidate Questionnaire (also includes senate candidate responses)
Australian Heritage Advocacy Alliance: Candidate Survey (It's a pdf, arranged alphabetical order by electorate - My responses are on page 22 & 23)
Australian Christian Lobby: Candidate Questionnaire
Stand up and Vote: Candidate Questionnaire
While I am not affiliated with any Senate candidates, I thought I'd help my fellow QLD voters by sharing the websites that I've found during research for my own vote.
