Her death shouldn't be in vain, she said on the website.
"We ask that the Australian Government and the state governments enforce the existing anti-bullying and harassment laws, and take action against those who violate them.
"We ask that social media companies take a more active role in the prevention of cyber-bullying, and take more responsibility in monitoring posts of 'hate'. We ask that together we unite to change the cyber-bullying platform."
Funeral details still hadn't been confirmed yesterday. Ms Dawson's sisters were expected in Sydney yesterday to begin planning the service with her closest friends.
A public memorial was expected to take place in Sydney, where she made her home, following a private cremation. It is also expected there will be a public memorial service in New Zealand.
A potentially world-leading bill introduced here in November, if passed, would address many of the issues raised from Dawson's case, and make it easier for the authorities to deal with cyber-bullies.
The Harmful Digital Communications Bill, introduced by Justice Minister Judith Collins, had its first reading in November. Public submissions on the bill closed last week and the select committee will consider those and report back on June 3.
"We expect it to pass by the end of the year," a ministerial aide said. "This is a priority of the minister's."
The minister said last night the legislation was world-leading: "What I'm hearing from my ministerial counterparts in Australia and the UK, for instance, is that their nations are also grappling with the challenges presented by increased communications within the cybersphere.
"I'm proud New Zealand is leading the world with our response to this global problem and nations around the world will be following New Zealand's Harmful Digital Communications Bill with interest," she said.
Proposals in the bill include: creating a specialised approved enforcement agency for cyber-bullying complaints; making it an offence to send or post harmful messages, punishable with a $2000 fine or three months' jail; and creating a new offence of inciting someone to commit suicide.
"This bill aims to create a new civil enforcement regime to reduce harm to victims, and new offences to ensure serious harmful digital communications can be prosecuted," a ministry spokesman said.
