Neighbours heard a terrifying 'blood-curdling" scream and a female begging not to be hit on the night a woman was killed outside a Gold Coast hinterland home.

Gaylene Cobby - known as Kym - was beaten and choked while taking out rubbish at her Worongary home on November 12, 2017.

Her estranged husband, Andrew John Cobby, 59, is standing trial for her murder.

Neighbour Gael Fitzgerald told Cobby's Supreme Court trial on Tuesday that she was woken by "thumping noises" the night of Ms Cobby's death.

"I heard a loud scream that came from a lady," Ms Fitzgerald said.

"Not long after that, I heard my dog barking, and then the neighbourhood dogs started barking.

"I heard a woman say, 'Don't hit me, don't hit me again'.

"I heard a muzzled, blood-curdling sound and then there was just silence.

"It sounded like someone was badly injured."

Security footage played to the jury earlier also detected the screams, with the Crown alleging it to be "the last moments of Kym Cobby's life", prosecutor Philip McCarthy said.

"Kym Cobby had been choked, asphyxiated, and left for dead," Mr McCarthy added.

He said the jury would hear a locked red Chrysler Cobby borrowed from his flatmate that evening was found near the body.

Cobby, 59, and his wife had lived separately from 2003 but remained married at the time of her death.

The trial will hear evidence of blood on his jeans and shirt that contained Ms Cobby's DNA, Mr McCarthy said.

Cobby admits being there with Ms Cobby but says he ran away into the bush when they were both assaulted by an unknown assailant.

Cobby has claimed his wife asked him to go to her hinterland home, concerned someone was at the house.

On the night of her death, he told police he tried to protect Ms Cobby but could not stop the assailant.

The jury is expected to hear from more than 50 witnesses over at least three weeks as the trial continues.
