The Cairns community has so far raised $45,000 to support the five-year-old son of Redlynch mum Claire Tucker, who passed away on Friday from injuries suffered when she fell from a bridge after a day out at the Cairns Cup. 

Her grieving family and friends launched the fundraising campaign in the wake of the tragic accident less than two weeks ago, with a goal to raise $100,000.

A coroner will now examine the circumstances surrounding her death with police finalising their report into the tragedy.

The Office of Liquor and Gaming Regulation has also confirmed to TropicNow the agency is not investigating any circumstances relating to Ms Tucker's day at the Cairns Cup or Cairns Jockey Club's management of the racing event.

Ms Tucker had been clinging to life in Cairns Hospital with serious injuries after being found in a drain at about 9pm on August 12 near Stockland Shopping Centre at Earlville.

She had been attending the Cairns Cup with friends earlier in the day when she became separated from the group. It is thought Ms Tucker had been trying to walk into town before she was found.

Her family is now mourning the loss of a much loved sister, mother, partner and daughter after making the heartbreaking decision to turn off her life support on Friday.

Claire’s mum Lesley Hill-Allen told News Corp she was still struggling to come to terms with the loss of her daughter.

"I get angry that it’s happened, it is so senseless,” she said.

"It's such a ridiculous accident that I can't imagine it has actually happened."

A funeral for Ms Tucker will be held in coming weeks.
