More than three years after the disappearance of 26-year-old Torrance Sambo near Sudbury Reef, his family say they are still searching for answers and justice.
Mr Sambo vanished on 16 October 2021 during a spear fishing trip with a work colleague.
According to police, he became separated during a dive and failed to return to the boat.
His body has never been found.
Despite an extensive search covering more than 135 square kilometres, only a small number of items were located on the ocean floor near the boat, including a wetsuit, speargun, mask, flipper and underwear.
Many discrepancies in the timeline of events have been pointed out by family members, IMPSS and the wider community.
One of Mr Sambo's sisters told National Indigenous Times only the underwear could be confirmed as his - and even that item had reportedly come from a spare set of clothes packed in his backpack.
"His clothes were never found... his blue reef shirt, black shorts, white hat, chain, sunglasses, and cigarettes - all missing," she said.
"We were told police had these things, but they were never returned."
She also questioned the decision to call off the search, the lack of forensic evidence collected, and the reliance on a single witness statement.
"How can anyone confirm he was on the boat if he was never seen at the boat ramp?" she said.
"Something happened between the servo and the water. That timeline doesn't make sense."
CCTV captured Mr Sambo at a service station with his brother around 12.45pm, where he bought a carton of beer and transferred his belongings to the boat.
CCTV also shows the colleague arriving alone at the boat ramp seven minutes later.
Mr Sambo was not seen again.
The family said they retraced the drive themselves - it took just over one minute.
They believe something happened in that missing window of time.
Later that day, a number of items were located by police divers near the anchored boat.
But community members, family, and advocates have questioned how clothing could remain intact while no remains were ever recovered despite Mr Sambo being allegedly taken by a reef shark.
The wetsuit, mask and other items allegedly used during the dive did not belong to Mr Sambo.
His sister confirmed they were borrowed and ill-fitting.
"It was a busted suit with a broken zipper - it would have weighed him down in the water," she said.
"The Torrance we know is very particular and he likes to take care of these things... he wouldn't even be in fresh water with his gold chain on, let alone salt water.
"Why would he go swimming or diving with his chain on it just didn't make sense."
The family also revealed that Mr Sambo's phone was returned to them by police completely wiped - factory reset.
According to the official timeline, Mr Sambo and his colleague met up with two men on a yacht that afternoon.
These men were not known to Mr Sambo before that day.
Their vessel - locally known in the region - was not searched by police.
No GPS data was retrieved from either vessel to confirm their movements.
The two men were part of the immediate search but soon left Cairns.
"They left Cairns within days," said Mr Sambo's sister.
"They never reached out to us. Nothing."
Another concerning detail raised by the family was the colleague's contact with Mr Sambo's partner in the days after the disappearance.
He allegedly told her he knew where she went to school, who her parents were, and other personal information.
She has since relocated out of Cairns as a result of these comments.
The official investigation concluded that Mr Sambo likely drowned and was taken by a shark, but many in the community say this explanation fails to address key inconsistencies.
IMPSS made a Facebook post in early June, detailing the key events of Mr Sambo's disappearance which quickly spread around Facebook, leaving many with more questions than answers.
"The so-called shark didn't ask this young man to strip off first before attacking," wrote one community member.
"It's insulting to suggest otherwise."
The family continues to call for the case to be reopened and properly investigated.
"We just want justice," his sister said.
"There are still so many what-ifs and unanswered questions. Torrance doesn't have a voice anymore, so we have to be that voice."
IMPSS has released episode two of its podcast series, which features two of Mr Sambo's sisters speaking about their experience with police, the broken promises they say were made, and the long fight for answers that continues.
Despite the coroner closing the case, Torrance Sambo's family and supporters say too many questions remain unanswered.
