Emergency services found Noah in the water with one of his arms severed.

A police officer went into the water and pulled him to safety before he was rushed to Sydney Children’s Hospital in a critical condition.

Mitchell was later found dead in the water and was unable to be revived.

Police are investigating whether the boys hit an obstacle while riding in the dark.

It is understood Noah’s condition has stabilised overnight.

Tributes have begun to flow online as devastated friends grieve Mitchell’s death and send well wishes to Noah.

One friend described Mitchell as the “purest boy you could ever meet”, who had “many great friendships” with his mates.

“Rest up lad, I’m going to miss you,” another boy wrote.

“Praying for you too Noah. Love you lad.”

“LLM (long live Mitch),” a third post read.

“You will never be forgotten.”

In recent weeks, Noah shared several videos on Instagram of his jet ski adventures with mates.

One video shows a jet ski rider blasting through a river before the vehicle ends up tangled in mangroves.

Another clip shows two boys riding a boat through a waterway, driving with its bow lifted in the air.

The alarm was first raised on Tuesday night when two girls on the shoreline saw the jet ski wreckage in the water and heard Noah calling out for help.

It is understood Mitchell’s distraught relatives were at the scene when his body was recovered from the water.

Inspector Timothy Carter described the officers’ actions as “heroic”.

“The police have done their best to try and save these kids’ lives,” he said.

“And it’s, you know, we obviously feel great empathy towards the families.”

Investigations into the crash continue.
