Aussies donate half a million dollars to murdered mum's family

Australians have dug deep to support Ashlee Good's family after the new mother was murdered in the Westfield shopping centre stabbing rampage on April 13.

More than $550,000 has been raised to support Ms Good's partner Dan as their baby Harriet recovers in hospital from the brutal attack.

"I hope you and your papa have a wonderful life together, knowing your mama loved you so much," one contributor said.

The fundraiser has far eclipsed the $100,000 target in just three days.

"Ash was a ray of sunshine and positivity in every aspect of her life and died a hero saving her little girl from the most unspeakable evil," the fundraiser, established by her former co-workers at Isagenix, said.

Killer Joel Cauchi stabbed the mother and her young baby after he entered the shopping centre just before 3.30pm.

He went on to kill another five people, Dawn Singleton, Yixuan Cheng, Faraz Tahir, Jade Young and Pikria Darchia, and injure a dozen others before he was shot dead by NSW Police inspector Amy Scott.

Aussies have also raised money for other victims of the vicious attack.

More than $32,000 has been raised for orphaned refugee Faraz Tahir, who was working as a security guard at the shopping centre.

The fundraiser said the money would be used to bring his devastated siblings to Australia to organise his burial.

Mother of two Jade Young also has a fundraiser in her name with more than $130,000 collected towards the $150,000 target.

"Jade has a loving husband and two beautiful daughters who need support in the following weeks and months," the fundraiser said.
