A mother whose three boys were murdered when their dad drove them into a dam on Father's Day has vowed to stop him from being buried beside his sons.
Robert Farquharson was on an access visit in September, 2005 when he drove the car in the dam and left his boys Jai, 10, Tyler, 7 and Bailey, 2 to drown.
His trial heard the murders were to punish his ex wife Cindy Gambino.
Farquharson has made arrangements to be buried beside the boys, the author of a book on the case, Megan Norris said on Monday.
Ms Gambino has vowed to fight the move.
"The night that he murdered the children he forfeited every right to be near them and that is my driving aim: I don't want him near my children ever again," she said at the launch of the book On Father's Day.
Ms Gambino also believes Farquharson's surname should be removed from her sons' graves.
She told the launch the book fulfilled the promise she made to her sons to be their voice.
"They lost the opportunity to live because someone just wanted sheer revenge on their mother," Ms Gambino told AAP.
Ms Gambino said Farquharson didn't shed a tear when he gave evidence at his trial and has never said sorry.
"He didn't do this because he didn't love his children," she said.
"He did this to `pay me back big time' were his words."
Ms Gambino hopes that by having her account of the murders published she may stop other similar killings from happening.
"I just want to get this message out that no matter what, just keep an eye out for any little sign because the smallest thing could turn into the most hugest thing in your life," she said.
Paramedic Dave Watson, who treated a dripping wet Farquharson beside the dam, said he came to the launch for some closure.
"At the court case the kids weren't there to speak up for themselves," he said.
"I was there, with other people, to give them a voice."
He was suspicious when he treated Farquharson on the night because of the way he conducted himself.
"I was suspicious at the time. You treat him as a patient, benefit of the doubt. But I was still suspicious, my partner was suspicious," Mr Watson told AAP.
"I made notes at the time because I knew this was going to be a court case."
Farquharson was jailed for life with a minimum term of 33 years in 2010.
His final avenue of appeal to the High Court was rejected in August.
