A coroner has found three people killed in a "freak" skydiving accident in Far North Queensland died in mid-air when a solo sports jumper's parachute opened prematurely, causing them to collide.

Findings from the coronial inquest, handed down in Cairns on Friday, will frame new safety regulations for solo sports jumpers which include more third-party equipment checks.

Coroner Nerida Wilson said experienced sports jumper Toby Turner, 34, made an "error of judgement" when he packed his parachute into an incompatible container before the accident in 2017.

Mr Turner was killed in mid-air when his chute opened, crashing into tandem jumpers Peter Dawson and Kerri Pike who were above him at the time.

A police investigation found a parachute used by the tandem jumpers was torn and saturated in blood, consistent with a mid-air collision.

The bodies of all three skydivers were found by residents in Mission Beach, south of Cairns.

In her findings, Coroner Wilson referred to a lack of regulation for solo sports jumpers.

"There is a culture in the skydiving industry which allows those with experience to self-regulate with regard to downsizing and container compatibility," she said.

"I take into account by comparison how thorough and regular the inspection and maintenance procedures were regarding tandem equipment."

Prior to the jump, Mr Turner was responsible for packing and maintaining his own equipment and wasn't required to undergo third-party checks.

The coroner said Mr Turner believed his equipment to be safe on the day of the jump.

'My family is in tatters'

She made several recommendations, including that the Australian Parachute Federation implement mandatory day-to-day buddy checks prior to boarding the plane and six-month equipment checks on all sports rigs.

Ms Pike's husband, Alister, said the recommendations were not harsh enough on solo jumpers.

"When you're dealing with the general public there should be no fuzzy lines and there is very, very disturbed fuzzy lines where the recreational industry meets commercialism. And that is the one that was so easy for [the coroner] to tidy up but she chose in my opinion not to," he said.

Ms Pike's family bought her a tandem jump with commercial operator Skydiving Australia for her birthday and Mr Turner joined them in the plane.

He said the inquest had not bought closure to his family.

"If I could be very frank here my family is in tatters," he said.

"I've tried to move forward but the cold hard reality is the kids are struggling, they're really struggling and that is central in my mind."

Mr Dawson's brother Jarred was also in court with his family as the coroner closed the inquest on Friday morning.

"It was a freak accident," he said.

"The next step is to ensure the recommendations are followed through."

The family cried and exchanged hugs in the court room as the coroner closed the inquest on Friday.

The Australian Parachute Federation, which regulates sports skydiving in conjunction with the Civil Aviation Safety Authority, said the findings would frame the introduction of new safety measures.

"The APF will review and consider all formal findings and recommendations issued by the Coroner today," CEO Richard McCooey said.

He said the APF has increased the number of safety personnel in Australia since the deaths.

"Safety is everything and follows proper education, regulation, a strict enforced safety process and a shared willingness by all involved to play their part," Mr McCooey said.
