The funeral of a mother killed in a helicopter collision on the Gold Coast is under way in Sydney.
Family and friends have gathered at Saint John the Beloved in Mount Druitt to farewell Vanessa Tadros.
Ms Tadros, 36, was one of four people killed when two helicopters collided and crashed into a sand bar near Sea World on January 2.
Ms Tadros' 10-year-old son Nicholas, who was in one of the helicopters with his mother, woke from a coma on Sunday but remains in a critical condition.
Pierre, a congregant in his 50s who declined to give his last name, told AAP the Tadros family were lovely.
"We feel so much pain. Vanessa was so pure-hearted - simply the best and kindest," he said
"Her mum is such a lovely lady who is so broken hearted."
The service is being conducted in Arabic and English by Coptic Orthodox and Lebanese Maronite priests.
British couple Ron and Diane Hughes and pilot Ashley Jenkinson were also killed in the crash.
Mr Jenkinson's funeral was held on the Gold Coast on Friday.
Air Transport Safety Bureau investigators are not expected to complete their probe into the accident until September 2024.
