During sentencing submissions in the NSW Supreme Court, Snibson painted herself as a victim of her accomplice Stacey Lea-Caton's violent outbursts.

The court also heard inferences that she had had an affair with Mr Hosa which she had threatened to reveal to Ms McKay.

The 38-year-old's claims contradicted the evidence of Lea-Caton and Andrew Wayne Flentjar, who denied her claims yesterday.

Snibson pleaded guilty in May to the January 2006 kidnapping and murders of the Nowra Hill couple.

Lea-Caton, 29, is serving a 22-year sentence for his role in the murders and Flentjar, 33, of East Nowra, is serving a 10-year sentence for assisting in kidnapping Mr Hosa and Ms McKay. He was acquitted of murdering them.

Cross-examining the two men yesterday, Snibson's lawyer Alex Radojev revealed his client's story as Flentjar and Lea-Caton repeatedly denied it.

Snibson also denied that she had ever recruited the two men into the crime.

She said she did not ask Lea-Caton to help her bash a couple who had videotaped themselves raping her.

Instead she said she told Lea-Caton about a videotape that had been dropped at her doorstep showing her and "Greg" holding hands and kissing.

"I said if I found out who (sent it) I would belt them," she said. "I embellished a bit and said it was a sexy tape."

Snibson denied telling Flentjar that she wanted to exact revenge on a person who had sent her a tape of themselves abusing a child.

Both men have said that they did not know the identity of the people Snibson wanted to assault, but they agreed to help.

There has never been any evidence that Ms McKay or Mr Hosa were involved in any sexual impropriety.

Flentjar and Lea-Caton have also repeatedly said that they had not met each other or Mr Hosa and Ms McKay before January 28, the day of the murders.

Mr Radojev said Snibson feared Lea-Caton's temper and did as she was told, buying bleach, forcing the bodies into the barrels and driving them to Tomerong State Forest where they were set alight.

He said Lea-Caton prevented her from going to the police as she had wanted to.

Lea-Caton said: "She's got a licence, she's got a car, why didn't she go?"

Both he and Flentjar have maintained that Snibson suffocated Ms McKay and strangled Mr Hosa.

The hearing continues today.
