Tracey Spicer says she will reveal the names of "long-term offenders" of sexual harassment in Australia's media industry, and has called on her social media followers to share their stories of harassment and abuse.

The veteran journalist, a regular contributor to Fairfax Media, said she was currently investigating two offenders but there are "plenty more".

She said she has already received a number of private messages from women, detailing harassment by powerful men in the industry.

"These are serial predators who've been enabled by their workplaces," Spicer told The Australian.
