Katrina Dawson's family remember her at Martin Place today.

Members of Katrina Dawson’s family visited Martin Place on Thursday afternoon to pay tributes to their lost relative.

Katrina Dawson, 38, died tragically in the Sydney siege. She was a Sydney barrister and mother-of-three.

The two males and two females, who are yet to be identified, left flowers at the Martin Place memorial, and held back tears as they noticed a letter written to Ms Dawson by one of her daughters:

They paused and took a photograph, then continued to look at the rest of the memorial.

Fairfax Media reports Ms Dawson, the daughter of a top QC, has three children aged under ten – two girls and a boy. The youngest child, a girl, is just four years old.

Ms Dawson attended Ascham and received a TER of 100. She also topped her bar exams, the Brisbane Times reports. The ABC reports her husband is Paul Smith, a partner at King & Wood Mallesons, the law firm where the couple first met. Ms Dawson worked at Selborne chambers on Phillip Street in Sydney’s CBD, just a minutes’ walk from the Lindt cafe.

It is understood Ms Dawson was getting a coffee with her work colleague at the time of the siege. The Australian reported her three children did not know she was a hostage until Tuesday morning.

“We are shocked and devastated by the tragic and senseless death of our darling Katrina,” Ms Dawson’s family said in a statement last night.

“She was an amazing woman and the most loving and loved wife, mother, daughter, sister, aunt, in-law and blessed with a wonderful circle of friends and ­colleagues.

“We would like to thank everyone who has provided their support and wishes over the past 48 hours and ask that we be allowed to support each other in private.”

The president of the NSW Bar Association, Jane Needham, SC, said it was “with a heavy heart and deep sorrow” that she informed members of the bar that Ms Dawson had died in the siege.

“Katrina, together with two other members of the NSW Bar, were held as hostages during the incident at the Lindt Cafe in Phillip Street, Sydney, yesterday,” Ms Needham said in a statement.

“Katrina was one of our best and brightest barristers who will be greatly missed by her colleagues and friends at the NSW Bar. She was a devoted mother of three children, and a valued member of her floor and of our bar community. Our thoughts are with her family at this time, including her brother, Sandy Dawson of Banco Chambers.

“Out of respect to Katrina’s family, the NSW Bar Association will be making no further comment at this time.”
