Good, who was tragically killed in the horrific Bondi stabbing, played with the Mermaids in the early 2000s.

Mermaids coach Louise Brown played a season with Good when they were both playing with the Victorian Country under 18 side in 2008.

"She was a lovely person," Ms Brown said.

"She was a great player with a bubbly personality. It's such a sad situation."

Ms Brown said there would be a minute's silence held before the Seahawks take on RMIT at The Arc on Saturday night.

The Mermaids play Camberwell away and will wear black armbands - as will the Seahawks players.

Good was described by her former Victorian Country coach Lee Primmer as a "gun player" with a huge heart.

Good, 38, defended her baby from the knife-wielding man in the tragedy that killed six people on April 13.

The osteopath died after Joel Cauchi, 40, attacked dozens of people - seemingly at random - at Westfield Bondi Junction on Saturday afternoon.

She was rushed to nearby St Vincent's Hospital in a critical condition but died that night.

Good, the daughter of former North Melbourne AFL player and board member Kerry Good, was remembered by her family as a "beautiful mother, daughter, sister, partner, friend" and an "all-round outstanding human".

Her nine-month-old daughter Harriet was also injured during the mass stabbing and is recovering in hospital.

Australians have dug deep to support the late mum's family.

More than $600,000 has been raised to support 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.
