Australia's Russian community is rallying to support grieving mother Olga Edwards after her two teenage children were shot dead by their father in Sydney.
Russian Speakers in Australia, a group that connects Russian speakers across the nation, has started a GoFundMe page to help support the 36-year-old.
As of Monday afternoon, more than $18,500 had been raised since it started on Saturday following the tragedy committed at Ms Edward's home in Sydney's leafy northwest suburbs.
Siblings Jack, 15, and Jennifer Edwards, 13, were executed in a bedroom at their West Pennant Hills home by their estranged father John Edwards.
Their mother arrived home to the horrific scene shortly after police and was treated by paramedics for severe shock.
Mr Edwards killed himself shortly after the shooting at his nearby home.
"The kids mum, Olga Edwards, is currently in a great distress and will possibly be out of work due to shock & bereavement for some time," the GoFundMe page says.
The funds will also go towards flying the children's grandmother from overseas to help Ms Edwards, the page says.
Dozens of people have sent their condolences to Ms Edwards on the fundraiser page.
"Please know that Jack was so loved by James; Jack was like a brother to James. James is missing him so much and is devastated ... Your beautiful babies, Jack and Jennifer, will be forever remembered by us," Jackie Leach posted.
While Margaret Best posted: "If only we could ease your pain just a little Olga! Our thoughts and prayers are with you. From ex students of Penno High and their mum."
Tributes have been pouring in on social media for Jack, who attended Pennant Hills High School and Jennifer who attended Gosford High School.
"Our hearts go out to the teachers, students and their families at Gosford High who have lost one of their own this week in horrific circumstances," Brie Rodgers posted on a Gosford community Facebook page.
The student leadership council at Pennant Hills High School said it was a "devastating" event.
"Today our hearts broke when we found out that one of our students was taken from us too soon," Penno Student Leadership Council said on Facebook.
