Two men who were found guilty over the death and violent sexual assault of Lynette Daley on a remote northern NSW beach in 2011 are due to be sentenced.
Ms Daley, 33, died on an Australia Day camping trip to Ten Mile Beach near Iluka from injuries sustained in the sex act with her boyfriend Attwater and his friend Maris.
A jury in September this year found Attwater, 43, guilty of manslaughter and aggravated sexual assault, and Maris, 47, guilty of aggravated sexual assault and hindering the discovery of evidence.
The five-week trial heard the trio had been drinking heavily and driving up and down the beach in Maris' troop carrier before Ms Daley was "repeatedly and vigorously" sexually assaulted on a mattress in the back of the vehicle.
The court heard Attwater only stopped the assault when he noticed blood on his hand.
Maris later burnt Ms Daley's bra and the bloodstained mattress "because it stank".
The Crown alleged Ms Daley was bleeding to death and Attwater didn't seek medical attention until it was too late.
Attwater and Maris are due to be sentenced at the Supreme Court in Coffs Harbour on Friday.
