A Canadian backpacker, who was found dead on an Australian beach and surrounded by a pack of dingoes earlier this week, likely died of drowning, an autopsy has found.

Piper James, 19, had "physical evidence consistent with drowning" and "injuries consistent with dingo bites", a spokesperson for the Coroners Court of Queensland told BBC news.

"Pre-mortem dingo bite marks" were unlikely to have caused her "immediate death", the spokesperson added. The autopsy was part of a preliminary assessment, and establishing her exact cause of death could take several weeks.

Piper's body was found on a beach on K'Gari, an island off the eastern state of Queensland on Monday.

In a statement to the BBC, the coroner also said there were "extensive post-mortem dingo bite marks" and that no evidence anyone else was involved.
