The Cockburns, who live in Young, lost their 15-month-old daughter Georgina when Mr Cockburn, a builder, was coming home from work and was reversing his tool trailer and ute into their garage.

Since the loss of Georgy, the family has set up the Georgina Josephine Foundation to help support families of such accidents, and raise awareness to the public, and government about how often these accidents (referred to as Low Speed Vehicle Runovers [LSVR]) occur, and what prevention methods could help reduce the risk of these tragic accidents.

On Sunday the couple were in Dubbo with foundation volunteers at the Dads for Kids Festival at Dubbo Showground with their Driveway Safety display.

The display shows ways parents can help keep children safe from vehicle, particularly in the home environment.

Mrs Cockburn said visitors to the foundation's display saw an example of an internal access door between the house and garage with the handle placed at least 1500 millimetres high with a self-closer, and a cut-off switch for an automatic roller door.

She said they also discussed the possibility of fencing the driveway or a safe area for children to play- away from cars.

"One participant mentioned how hard that was to do when living in a rental property. Landlords are encouraged to look at providing safe fenced off areas for tenants' children to play - thinking of it as a 'duty-of-care' towards tenants," she said.

Participants were also invited to look at the blind-spot display to see how many children (cardboard cutouts in this case) standing in a 10-metre space behind a car could not be seen in the mirrors of a vehicle, and what difference a rear vision camera makes.

"They saw how a new reversing system, Reverse Alert (not yet on the market) works through the use of thermal sensors, and engaging the vehicle's brake when sensing an object while the car is reversing," she said.

"Above all awareness and supervision are key - if mum or dad is moving the car, who has the kids, are they in a secure place?"

Mrs Cockburn said getting into the habit of routine checks was another important safety factor.

"Every time you get in the car to drive, no matter where you are, do a 'circle of safety' around the car to check no one is in the way," she said.

Former Australian and Balmain rugby league legend Wayne Pearce "had the opportunity to see just how much you can't see at the rear of the vehicle" when he sat in the driver's seat of the display vehicle during a live demonstration.

"With more than 30 children and adults sitting on the 10-metre mat stretching behind the rear of the sedan he could only see the top of four people, demonstrating the huge blindspot that is behind vehicles," Mrs Cockburn said.

"The Georgina Josephine Foundation would like to thank the team at UnitingCare Burnside for inviting us to be a part of the day, Wayne Pearce for being involved with our live display, as well as all those who participated on the day."
