The vengeful father who murdered his three sons by driving them into a Victorian dam on Father's Day wants to be buried next to them.
But Robert Farquharson's former wife Cindy Gambino says she will fight to ensure he is never near their sons again.
Farquharson drove into a dam in Winchelsea in 2005 during an access visit and escaped the car while 10-year-old Jai, seven-year-old Tyler and two-year-old Bailey drowned.
His trial heard the murders were to punish Ms Gambino.
The author of a book on the case, Megan Norris, says Farquharson made arrangements while planning the children's burials that he would one day be interred beside his sons so he could permanently punish Ms Gambino.
Ms Gambino told the book launch for On Father's Day that Farquharson has no right to be near the children.
"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 on Monday.
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.
