NetSafe executive director Martin Cocker says on average, NetSafe receives around 1000 reports of online harassment a year.
"Everything from one-off online abuse and trolling through to cyber-bullying campaigns, which are ongoing," he said.
Forms of online harassment reported in the Norton survey ranged from unwanted contact, trolling and character assassinations through to threats of physical violence, rape and death.
Norton by Symantec's Asia Pacific senior director, Melissa Dempsey said women reported feeling violated, abused and frightened by their online experiences.
More than 21 per cent, or one in five, women reported feeling depressed, and 17 per cent felt helpless. Women also reported feelings of anger, frustration and anxiety.
Those results are concerning, said Dempsey.
Perhaps even more concerning is despite more than 70 per cent of women identifying online harassment as a serious problem, only nine per cent of women affected will report the harassment.
Dempsey says that could be due to a lack of awareness around what sort of help is available.
But Emily isn't surprised at those figures. She says it's hard for women to feel like they'll be taken seriously if they complain.
"Women are told all the time to just accept it. It's very rare for a woman to be taken seriously when they say they're being abused online.
"I think every piece of writing I've ever done, I've had at least one comment that says 'you chose to put yourself out there, therefore whatever you get, you deserve it'," she said.
Solutions to online harassment vary.
Dempsey believes it's important to raise awareness of the help available and Mr Cocker recommends getting professional advice, depending on the situation.
But Emily says it's about changing attitudes.
"It's not for women, it's for men. If you [men] see what men are saying to women online - say something because when they [abusers] hear it from men it'll mean something."
Emily says a lot of women can't speak out about it or push back because it can escalate the abuse.
"I really think it's up to men to be saying to other men, 'hey, this is how you're meant to be behaving online'.
"Because a lot of it is what can women do, what should women do and I actually think the conversation should be moved to men sorting out their mates."
