THEIR beautiful daughter Sara Zelenak was only 21 when her life was cruelly ended by Islamic terrorists at London's Borough Market.
Her murder almost two years ago caused ripples of grief across the Redlands as her family and friends back home dealt with the traumatic loss.
Sara's parents Julie and Mark Wallace could have become debilitated by the chaos but instead are helping others to overcome agony caused by the violent or sudden death of loved ones.
The Wallaces are planning to set up traumatic grief retreats in countries like Australia, the UK, France and the United States in Sara’s honour, which will offer traditional and alternative therapies to help people heal.
Their mission would also ensure the way Sara lived her life - in light, happiness and freedom - would be her lasting legacy to the world.
The Wallaces launched charity Sarz Sanctuary last year to help them achieve their mission, also turning their Meet You in Paris ride from London Bridge to the Eiffel Tower into an annual fundraising event for the cause.

Ms Wallace said everyone was invited to sign up for the fun ride from London to Paris on from June 23 to 29.
The event had already attracted cyclists with bikes designed for carting champagne, tandem riders and participants keen to dress up in fancy dress for the cause.
A fundraising target of $2000 needed to be achieved by ride participants who have until April 1 to sign up.
The entourage would first assemble at Elliot's restaurant and wine bar at London's Borough Market for a meet-and-greet the evening before the ride.
The restaurant employs Australian woman Candice Hedge who survived the June 2017 terrorist attack and who is helping the Wallaces out on their mission.
Ms Wallace said the partner of Australian woman Kirsty Boden, who received a Queen's bravery award posthumously for trying to help others in the terrorist attack before she was killed, would also be riding in the Meet You in Paris event.
Ms Wallace said so many people had reached out to her for help or to offer their assistance to the cause that she had left her job at Healthworks Fitness to commit full-time hours to Sarz Sanctuary.
The Wallaces were also seeking charitable status for Sarz Sanctuary in the United Kingdom, which they hoped would granted before an inquest into the London Bridge terror attack began on May 7.
"We are planning to grow Sarz Sanctuary worldwide," Ms Wallace said.
Ms Wallace encouraged individuals and businesses to help them on their mission by participating in a virtual Meet You in Paris ride. More information can be found at meetyouinparis.com.au.
She said corporations could sign up to have an exercise bike dropped off for employees to participate
"It is about keeping people performing well at work," Ms Wallace said. "You get tired and slack (sitting down) and people are already getting stand-up desks."
She said Cover-More Travel Insurance, who had insured Sara, would put stationary exercise bikes in their offices for the ride.
The insurer had also recruited the Wallaces to promote staff wellness programs.
The Wallaces will appear on the Morning Show on Wednesday, March 13 and are also hosting a fundraising trivia night on April 13.
