Mechelle Turvey has donated generously to community groups that played a role in the life of her late son, Cassius.

Eight months have passed since the death of 15 year-old Noongar boy Cassius Turvey and his absence is still strongly felt by those close to him.

On Tuesday a group gathered at the Swan City Youth Centre (SCYC) as Ms Turvey donated up to $20,000 each to groups that supported her late son.

Cassius was attacked when he was walking home from school on October 13, and died in hospital 10 days later. His death shocked the nation and sparked rallies and an outcry around the whole country.

The community groups honoured by Ms Turvey's donations are Koya Aboriginal Corporation, Binar futures, the Lawn Mowing Boys, and the SCYC.

Before Ms Turvey presented the groups with the donations, she wanted to send a message to those in attendance.

"I think of all the other people that helped raise Cassius and all these young people, " said Ms Truvey.

"My niece has this saying that children are raised by a village."

After Cassius' passing many of his friends stopped hanging out at the SCYC, a place that had sentimental value to the teenager as the centre is where he spent most of his time.

"Unfortunately where we stand today, a lot of the children have stopped going, they stopped coming here, because they can no longer come here with Cassius," said Ms Turvey.

"I'm telling all you kids now and spread the word, raise up, you are all leaders, be responsible…"

"Cassius might have been a little mentor or leader and when you buzzed out a problem, you'd go to him.

"He gave everything that he could to be helpful and to be part of a family and to be the best resident he could be in his village. This is your village"

Ms Turvey urged young people affected by Cassius's death to return to SCYS and to use the services that the centre offers them.

The centre held a special place in Cassius' heart and now it does for Ms Turvey. Cassius would play basketball on Tuesdays and he made sure to be there every time there was a sausage sizzle.

"I try to do as much as I can to wrap around Cassius, what he was, what he used to do, his relationship and now unfortunately I'm here to carry on his legacy," said Ms Turvey.

"But I won't carry it alone, you kids are going to help me, you understand?"

Among those who attended were some of Cassius' school mates and kids he knew in his community. Ms Turvey wanted to make sure they stay strong and focus.

"Cassius would not want people mourning day and night for him, that's why he had that smile on his face, who ever saw him without that smile?" she said.

The donations to the four groups were funded by a gofundme campaign.

Koya Aboriginal Corporation.

Cassius started off at Koya first and Ms Turvey wanted to present them with $20,000 for what they do for kids and their community.

Binar futures.

Cassius was part of the basketball program with Binar basketball. He would spend a great deal of his time at the program. Ms Turvey donated $20,000.

The Binar girls put on a performance for the event, dedicating their dance to Cassius.

Swan City Youth Centre (SCYC)

Ms Truvey met the owner of SCYC centre, Ray Tanielu a fortnight ago. Upon her visit to the centre Mr Tanielu showed her where and what her son would do when he was here.

When she informed Mr Tanielu that she would like to donate money to the centre, he broke down with gratitude. SCYC also received $20,000.

The LawnMowing Boys

Cassius started off with the LawnMowing boys with his friend that eventually grew to a small group of boys going around mowing lawns in their community.

The reason for starting up their community service group was because they didn't want people to think that they were "bad kids".

One of the boys, T'Shawn, spoke on behalf of the group members.

"I want to say it feels good that everyone is back here..it feels good that the community is back together…like the old times were," he said.

"I'm honoured to be up here for the lawn mowing boys and to continue it on for him, he definitely would love that."

Each four boys received a package that consisted of gift cards for Bunnings, fuel and clothes that valued five thousand dollars.
