Sue Maslin, one of the most successful film and television producers in Australia, has seen efforts to address sexual harassment and gender imbalance in her industry come and go, time and again.

In her 35 years in the business, producing films including The Dressmaker and Japanese Story, official cases of harassment and indecent assault were few and far between, and the women who made the complaints were often left isolated.

Not any more.

The #metoo and #timesup movements, prompted partly by the numerous allegations of sexual assault and harassment by Hollywood producer Harvey Weinstein over several decades, and against other entertainment figures since, has put abusers on notice.

"What is different now is that women are finding the voice, the courage and the support to come forward, and for the first time calling out the behaviour," Ms Maslin said.

She's a patron of Women In Film and Television Victoria, which will hold an industry forum this month to discuss ways of addressing sexual harassment and indecent assault in the workplace.

"It’s not about sexuality, it’s about power, and it’s about adjusting the power balance in our screen culture," Ms Maslin said.

"What’s so significant about the current scenario is that this is not about individual women and their experience. It is systemic. It’s part of our culture. It is a continuum where sexual harassment is just one end of a continuum of behaviour that sits within the culture.

"What is different is that if the behaviour continues, men know that they will be held accountable. That’s the difference."

Ms Maslin will speak at the forum alongside journalist Tracey Spicer, who has spent months investigating cases of sexual harassment and indecent assault in Australia's media and entertainment sector.

Maslin sees what is now happening as a "flashpoint" that could finally change that culture for good.

"What’s exciting about the current moment – and I have seen these moments come and go for 30 years now – is that there is a genuine possibility for change now, because there’s a realisation that both men and women are being done a disservice, and audiences are being done a disservice, by not having women equally part of the culture."

Maslin, who is now working with The Dressmaker director Jocelyn Moorhouse on another film, is president of the Natalie Miller Fellowship, which supports the professional leadership of women in the screen industry.

The fellowship, along with Film Australia's $5 million Gender Matters project, are helping reddress the gender imbalance within the  industry, through which a number of films made by women will be released by the end of this year.

"We have this unique opportunity over the next five to 10 years, there will be generational change. We’re already seeing it right now.  And there will be increasingly more opportunity for women to step into the ranks of the baby boomers, who thank God – and I’m one of them – will be moving on ...

"It's an industry that was largely driven by men in their 20s and 30s back in the '70s and '80s and then as they got older the industry got older. But it’s time for renewal and perhaps why this flashpoint is not going to go very quickly.

"I genuinely believe that this greater accountability, greater awareness, timed with generational change, will bring about ongoing change."

Women in Film and Television Victoria board member Diana Fisk, who is organising the February 26 forum, said the impetus for the event came partly out of her own experience in the industry.

"I personally have had a #metoo experience, and when this all happened, with #timesup too, I said to the board we need to do more on this," Ms Fisk said.

"As a filmmaker I didn’t know where to go, what to do," she said.

The forum would help women working in the industry find out what to do.

"Everybody’s involved for that reason," Ms Fisk said.

"There's still a lot of fear in speaking up, among men too in terms of what they’ve witnessed."

Time’s Up - A Forum For Change is at The Pavilion Room, Arts Centre Melbourne, from 6.30-9.3pm on Monday, February 26.
