The family of a 19‑year‑old woman found dead on a popular Queensland island — surrounded by a pack of dingoes — may never learn exactly what happened in her final moments.

Piper James’ father, Todd, says he received the autopsy and toxicology results late on Thursday night, revealing the findings are inconclusive.

Piper was found dead near the surf at the Maheno Wreck about 6am on Monday.

It is understood Piper left for a swim at 5am, with passers-by discovering her body about an hour later.

A small group of dingoes was found around her body, with police confirming the animals had come into contact with her.

A Queensland Coroner’s Court spokesperson confirmed in a statement they are awaiting pathology results to help determine the cause of death, which will take several weeks.

“The autopsy has found physical evidence consistent with drowning and injures consistent with dingo bites. Pre-mortem dingo bite marks are not likely to have caused immediate death,” the spokesperson said in a statement.

“There are extensive post-mortem dingo bite marks.

“There is no evidence that any other person was involved.”

Meanwhile, Piper’s father was warned by investigators it could take up to two more months before the cause of death may be identified.

Even then, Todd says, the truth may remain out of reach.

Piper’s father is delaying his trip to Australia until he knows when he’ll be able to formally farewell his daughter.

In the meantime, he wants to meet with the Queensland Premier to push for safety changes on the island to prevent another tragedy.

He says Piper adored nature and animals and would never have supported a dingo cull — but he believes urgent safety improvements are needed.

Among the measures he wants considered are stronger training for island staff, mandatory carrying of dingo sticks, and even a ban on children under 13 visiting K’gari.

Local community members have raised fears the young woman’s death will spark a culling of the island’s dingo population, with Queensland Premier David Crisafulli not ruling anything out.

Traditional owners have argued against a cull, instead calling for a cap on visitors and introducing periodic island closures.

K’gari reportedly attracts about 500,000 visitors annually, but the traditional owners believe the real figure is closer to 800,000.
