Senior executives from Australia's major media organisations are preparing to state a united case for a major rethink on balancing press freedom and national security.
The heads of various media organisations will front federal parliament's powerful intelligence and security committee in Sydney on Tuesday.
Their joint appearance comes after Australian Federal Police raids on the Canberra home of a News Corp journalist and the Sydney office of the ABC over separate investigations into government leaks.
The AFP raids were widely condemned as heavy-handed and for having a chilling effect on reporting.
Senior figures from the ABC will also appear before the committee, along with various human rights and legal advocates.
