Q&A: George Bender's daughter accuses politicians of neglecting farmers

Helen Bender, whose father killed himself after long battle against coal seam gas, tells program's panel: 'I don't believe any one of you politicians have listened'

The Nationals senator Fiona Nash has called for state laws enabling landholders to refuse access to gas companies, saying they are the "simple answer" to an issue brought into focus by the suicide of a Queensland farmer.

Nash told the ABC's Q&A program states should make the necessary changes to empower farmers, and gas projects affecting residents nearby should be put on hold pending further study of their health impacts.
