Rockingham boy critically injured in Bali quad bike crash

An eight-year-old Rockingham boy has suffered critical head injuries in a quad bike crash in Bali.

Joshua Scheutz and his family were in Ubud where the young soccer star was due to play in a tournament with his Cockburn Wolves Futsal team on Saturday.

Family friend BJ Ariasa told 7News Josh was a pillion passenger on a quad bike being driven by his older brother when it flipped into a rice field on Wednesday afternoon.

“(The quad bike) just slipped off the pathway and into a rice field which was filled with water so Joshy was pinned underneath the bike with a harness on attaching him to the bike and in the water,” Ms Ariasa said.

“So (his older brother) Luca ... pulled him out of the water with some kind of superhuman strength."

Tragically, Josh suffered a fractured skull and a brain bleed and underwent emergency surgery.

He is now in a coma with a team of Australian doctors and nurses on standby to bring the little soccer star home where he will be treated at Perth Children's Hospital.

Ms Ariasa has set up a GoFundMe page to help pay for Josh's hospital bills.

It has already raised over $70,000.

It's understood Josh's family did have travel insurance but it only covers the medivac flight home and not hospital bills which are set to exceed $100,000.
