Australian billionaire and philanthropist Judith Neilson has committed $100 million for a new journalism institute to be based in Sydney.

The Judith Neilson Institute for Journalism & Ideas, which promises to be independent and non-partisan, will seek to encourage quality journalism through education and grants, and by hosting events on topical issues.

“As an avid consumer of news, I recognise the need to support evidence-based journalism and the pursuit of truth in an increasingly complicated and confusing world,” Ms Neilson said.

Ms Neilson acknowledged the digital disruption affecting journalism in Australia, saying it "needs a shot in the arm".
