The global gold standard for bringing down a sexual predator is Ronan Farrow’s relentless pursuit of Harvey Weinstein, exhaustively chronicled in his book Catch and Kill

But here in Australia, because of the differences between US and Australian defamation law, the big catches have not been reeled in by the media but by the (so far) rare instances of institutional leaders being prepared to call powerful perpetrators to account.

Our incoming defamation law reforms, which will create a public interest defence for investigative reporting, are the first of three major legal developments that I believe are prerequisites to a genuine change of culture around sexual harassment in the workplace. The other two are starkly illustrated in Farrow’s book.
