Warning: video contains content that may upset some people
Cockpit video has emerged of a passenger trying to warn a pilot seconds before two helicopters collided in mid-air on the Gold Coast, killing four people and critically injuring two boys.
Nicholas Tadros (10) from Glenmore Park in Sydney and Leon de Silva (9) from Geelong West remain in intensive care in southeast Queensland hospitals after the collision near Sea World on Monday afternoon.
Nicholas' mother Vanessa Tadros (36) was among the four people killed in the crash, while Leon's mother Winnie De Silva (33) was seriously injured when the helicopter lost its main rotor and crashed heavily on a sandbar.
The crash also killed British-born pilot Ashley Jenkinson (40) and Ron and Diane Hughes (65 and 57) from Liverpool in the UK.
A video taken inside the second helicopter leading up to the crash has been broadcast by 7News which appears to show one of the passengers trying to warn the pilot by tapping him on the shoulder.
Seconds after the passenger attempts to get the pilot's attention, the video shows the helicopter's interior being struck by flying glass as the first aircraft's main rotor strikes the cockpit.
The pilot and all five passengers in the second helicopter survived, with all but one suffering shrapnel injuries.
A Queensland Health spokesperson on Wednesday said a total of four people from both helicopters were still in hospital in a stable condition, including Ms De Silva, and Nicholas was in critical condition.
A Children's Health Queensland spokesperson said Leon was also in a critical condition.
The Australian Coptic Movement Association for the North African Christian community said it had reached out to the Tadros family to see if it could offer assistance and asked its members to join in prayer for Nicholas.
The Lara Giants Basketball Club, which is based just outside Geelong, said one of its members had been deeply affected by the crash and called on supporters to donate to an online fundraiser for Leon, as did the Kenya Community Victoria group.
On Wednesday, Vanessa's husband Simon informed the customers of his wife's wedding decoration company that she had died.
"It is with great sadness and a heavy heart that I have to inform everyone of the passing of my beautiful wife ... While my son is fighting for life in the ICU," Mr Tadros stated.
Winnie's husband Neil De Silva told Nine News that it had been a "pretty tough" time for the family and her condition was improving.
"They operated on her major leg break (on Tuesday) and finally washed the aviation fuel off her so she was able to talk and feeling better this morning but our major concern is Leon - when they wake him up (on Wednesday) - that he is OK," Mr de Silva said.
