Ivan Milat’s long-time mistress says she will never forget him and worries about him every day

Ivan Milat’s mistress and former sister-in-law has broken her silence and confessed her unconditional love for Australia’s most notorious serial killer.

Marilyn Milat-Tempest said she worries about her lover everyday as he battles throat and stomach cancer in Sydney’s Long Bay prison, where he is currently serving seven life sentences.

Ms Milat-Tempest told The Daily Telegraph she thinks still thinks about Milat and ‘doesn’t want him to die’. 

‘He’s sick, I don’t love him like that anymore, well… I always will… I’ve kept the name all these years,’ she said.

‘Ivan is Ivan, he’s different to anyone I’ve met. In his last days I can’t forget (him) … I worry for his health.’ 

The pair began their affair in the early 1960’s, while Ms Milat-Tempest was in a relationship with the killer’s brother, Boris, while he was living with wife Karen and their children in Western Sydney.

It’s believed when Boris would work away from home, Milat would visit their home in Woy Woy where they would continue the affair.

The affair lasted 11 years and soon divided the family in 1965 when Ms Milat-Tempest gave birth to Lynise – which became known to be Milat’s love child.

Milat’s brother was suspicious of the affair and threatened to leave with her daughters if she didn’t cut things off.

Even now, decades after the affair Ms Milat-Tempest still worries for the killer, with many who know her saying she keeps tabs on Milat.

‘I worry for him, I call Long Bay jail almost every day to see how he’s doing, they tell me he’s OK,’ she said. 

Milat was jailed in 1996 after being convicted of murdering seven backpackers in the Belanglo State Forest, south of Sydney, between 1989 and 1992.

Milat’s victims included three backpackers from Germany, another two tourists from Britain and two Australian travellers from Melbourne. 

He has spent most most of the last two-and-a-half decades in Goulburn’s Supermax prison, the strictest in Australia. 

He has left the prison on just two other occasions – once in 2001 for a court appearance and once in 2009 when he cut off one of his fingers. 

But despite a mountain of evidence against him, he has never confessed.

Milat is currently serving seven life sentences, which are all to be served consecutively and without the possibility of parole.

He stabbed most of his victims – decapitating one whose head has never been found – and shot another 10 times in the head as if using her for target practice.

He was also questioned in 2004 about the disappearance of two nurses at Parramatta in 1980 when he was working at the nearby Granville depot of the then Department of Main Roads.

In 2006 Milat was named by police at an inquest as the person most likely to have killed a schoolgirl and her boyfriend who disappeared from northern Sydney in 1978.

Late last year, Milat wrote a 10-page letter proclaiming his innocence.
