'We really hope we've changed people's attitudes': Hornby twins' legacy lives on in campaign

The five-year-old sisters, along with their grandmother Denise Mansell, were killed in a motor vehicle accident on the Sunshine Coast when a speeding driver slammed into their car.

The driver of the other vehicle, 43-year-old Anthony Paul Thomson, was also killed in the crash.

An inquest heard Mr Thomson was on a combination of prescription drugs to treat mental and physical illnesses at the time.

Cannabis was also found in his blood and his lights were faulty.

The tragedy galvanised the communities of Blayney and Orange where the girls' parents Kellie and Michael Hornby had family.

The late Mr Hornby, who died of cancer five years after the accident at aged 43, was the brother of Adam Hornby - the president of the Orange and District Cricket Association at the time and a long time supporter of the Bears club and Group 10 rugby league.

This week the girls' aunt Danielle Oresic handed over the latest donation, to Ronald McDonald House in Orange and the children's ward at Orange Health Service.

She said their fundraisers for 10 years had been 'Pink and Purple days', as they were the twins favourite colours.

"We really hope that in the 10 years we ran the fundraising awareness days, it may have had an impact on changing people's attitudes to importance of road safety awareness ," she said.

Executive Officer of RMH Rebecca Walsh said she was humbled the final donation was going to the house.

"What the family went through, first with the loss of the girls and their grandmother, and then just a few years later with the passing of their dad Michael, is just overwhelming and hard to imagine.

"But in the midst of all of that, how humbled we are here at Ronald McDonald House to be the recipient of the family and supporter's generosity," Ms Walsh said.

Mrs Oresic thanked everyone who had been involved in the fundraising.

She said RMH does important work.

"To think that families can stay free of charge and don't have the worry of having to keep driving back and forward to their home is wonderful," she said.
