But one of the men, Travis Clare, told the inquest he refuted this allegation and said the group didn’t immediately raise the alarm about Mr Rivers’s disappearance because they feared the repercussions of breaching the border.
Matthew Perris told police he received a Facebook call from his cousin, Mr Rivers, begging him to come and pick him up after a fist-fight with one of the men on the trip, Joe Joe Kantilla-Gaden.
He claimed this was after Mr Rivers found out about the drugs and “wanted out”.
Mr Kantilla-Gaden disputed the claim and denied that a fight had occurred. He said he had been attempting to stop Mr Rivers from walking off, who he alleged had been awake for multiple days, drinking and smoking methamphetamine.
‘Lies and inconsistencies’
On Thursday, Mr MacKenzie said it “would be pure speculation that all the group were involved”.
He also said the “lies and inconsistencies” could be “explained away as a means of avoiding prosecution from trafficking dangerous drugs into the Northern Territory … or the group illegally breaching COVID-19 restrictions”.
The coroner found the police search costed hundreds of thousands of dollars and was well-resourced despite the difficult terrain and weather conditions.
“The biggest hurdle to an effective, early and constructive timely search … [was that] 30 hours had elapsed before Jayo’s disappearance was officially reported.”
But he said a notebook entry by a constable about Mr Rivers going “walkabout on occasion” was “concerning”.
He also said it was “very disappointing” that “the important evidence” from Mr Perris about the Facebook call was not acted upon much sooner than early 2022.
A police investigation remains open. The coroner’s findings note that since the inquest was held, QPS has carried out a 16-day police and SES search of 68 square kilometres north-west of Noccundra.
