Brittany Higgins says she is committed to appearing before civil proceedings brought by former colleague Bruce Lehrmann.
Mr Lehrmann has launched defamation action against Network Ten and News Life Media, the News Corp Australia company behind News.com.au, over their coverage of rape allegations made by Ms Higgins.
On Tuesday afternoon, his lawyers filed statements of claim in the Federal Court against the media outlets. Lisa Wilkinson, host of Channel Ten show The Project, and News political editor Samantha Maiden have also been sued.
