The family of Matthew Leveson has turned up at a crime scene south of Sydney where police have been searching for the missing man's body.
Mr Leveson's mother, father and siblings arrived at the Royal National Park near Waterfall about 5.30pm on Thursday after police called off the search for the day for the 20-year-old, who disappeared in 2007.
A young man who arrived with the family, believed to be Mr Leveson's brother, reportedly swore at photographers and media.
Police were led to the site by Mr Leveson's former boyfriend, Michael Atkins, who was previously acquitted of the 20-year-old's murder.
Mr Atkins has been grilled this month at an ongoing inquest into Mr Leveson's death.
More than nine years after Matthew Leveson disappeared, his family may be a step closer to finding his body as his former boyfriend led NSW police to a bushland search for his remains.
Mr Leveson's partner Michael Atkins, who was acquitted of the 20-year-old's murder at a trial in 2009, led police to the Royal National Park, south of Sydney.
A group of loved ones including Mr Leveson's parents visited the site on Thursday afternoon, where they comforted each other, spoke to officers, and stood outside police tape looking down a dirt bush track.
Police at the scene told reporters the search would continue with sniffer dogs on Friday.
Mr Leveson's father, Mark, earlier told reporters they had been asked not to speak to media.
"At the moment, you know more than we do," his mother Faye, who carried a bag adorned with pictures of her son, said outside Glebe Coroner's Court.
The family and a crowd of journalists had waited at the court for most of the day but the inquest did not resume as scheduled.
The search comes after Mr Atkins copped a five-day grilling last week at the inquest into Mr Leveson's disappearance.
He was given immunity from prosecution before he was forced to testify at the inquest, where he said he thought Mr Leveson may still be alive and possibly living in Thailand.
Mr Leveson was last seen leaving the ARQ nightclub in Darlinghurst with Mr Atkins in 2007.
On the day of the disappearance, Mr Atkins was captured on CCTV buying a mattock and duct tape with the receipt later found in Mr Leveson's abandoned car, the court heard.
He told the inquest he bought the equipment for gardening at their Cronulla unit in Sydney's south, but agreed the mattock could be used for digging graves.
"Somewhere like the national park down south where you lived, agree?" counsel assisting the coroner Lester Fernandez asked.
"Could be anywhere," Mr Atkins said.
The court also heard Mr Atkins had sex with another man in the days after Mr Leveson went missing.
On his final day of testimony he denied killing his lover, saying he was sorry for the family's heartache.
Deputy State Coroner Elaine Truscott has previously noted "the family's all-consuming need simply to learn what happened to Mr Leveson, even at the price of foreclosing any further criminal prosecution".
According to criminal law expert Dr Thalia Anthony, Mr Atkins would likely not be charged even if he divulged the whereabouts to police outside of the inquest proceedings.
She said the certificate of immunity would likely also cover him from civil action.
"I think anything that is produced for the benefit of the coroner, and this would be included in that, would be covered by the immunity," she told AAP.
The inquest has been adjourned until further notice.
