Tragically, they never made it.

The four-year-old boy died in a crash involving a truck and three cars on the Monaro Highway at Hume, near Mugga Lane, on July 28.

Now, the Canberra community is rallying around Blake's parents, Camille and Andrew, and his two-year-old brother Aidan.

With the family's blessing, members of a mothers' group that Camille set up are trying to raise $10,000 to ease some of the financial pressure Blake's grieving family is now facing.

The money will also allow the family to set up a memorial for Blake, described by his aunty Christine Heard days after the crash as an intelligent and inquisitive boy who loved his toy trains and puzzles.

There has been an outpouring of support for Blake's family since the crash.

At his funeral, where 120 chairs were put out, it was standing room only.

Police officers and the first person who stopped to help the family at the scene of the crash were among those who attended to show their support.

On Sunday morning, six days after members of the mothers' group set up a GoFundMe page, more than $8600 of the $10,000 target had been raised.

Kylie Ingram, a member of the mothers' group, said the response had been heartwarming.

"It's completely blown our minds, the amount that people have given," she said.

"It's mainly Canberra people [donating], but some of them have been international people.

"People's generosity is just amazing."

Blake's parents said they would like to thank the community for the support they had received.

An ACT Policing spokesperson, when asked if any charges had been laid in relation to the crash, said the investigation was ongoing.

"We will provide further details when we are able to," the spokesperson said.
