That's how much the Ricky Stuart Foundation stands to win if Media Award salutes in the $7.5 million race at Rosehill on Saturday.

And Stuart already has the perfect project to put it towards.

He's got the land - the Village Building Company have given him a block at South Jerrabomberra.

Now he needs to raise $4 million to build the house - which will be used to house six young adults who are living with a disability, while also providing full care for them in independent living.

It will be on top of the two respite houses Stuart's already built in the ACT.

He's a keen follower of racing, owning a few horses himself, but there'll be a bit more riding on this one when he sits down to watch The Golden Eagle on Saturday.

Each one of the 18 runners has nominated a charity or foundation who they're racing for, with 10 per cent of the prize money going to a good cause.

Stuart was full of praise for Racing NSW for the Golden Eagle concept - which he said was not only part of the reinvigoration of racing, but also was a massive boost for a lot of worthy causes.

"I'll certainly be watching it with greater interest now," Stuart said.

"We're very fortunate to be the recipient of having a horse in The Golden Eagle.

"A win there would kick off the fundraising very, very well with the 10 per cent of the prize money going to a charity.

"The concept of what Peter V'landys and Racing NSW has created not only had the racing profile in NSW go through the roof, but there's the wonderful concept of having each horse having a relationship with a charity or foundation."

Stuart knew who Chris Calthorpe was, but he hadn't had the chance to meet him - until the Geelong trainer revealed his Media Award would be racing for his foundation.

Now they've enjoyed a chat during the week, where they were able to talk about their common bond.

Calthorpe's son Archie has Asperger's syndrome, while Stuart's daughter Emma has autism and he named the second house he built after her.

Emma was the reason Stuart started his foundation, so he could help others.

Now he and Calthorpe are set to do that together.

"I had the pleasure of talking to him this week and we discussed at length the situation we faced as a family because he has a young son, Archie, who is also on the spectrum with Asperger's," Stuart said.

"We had a great chat from a family point of view in regards to the challenges and what it brings to a family.

"From a foundation point of view it was brought about for the opportunity to help other people.

"Chris was great and very bullish about Media Award running well. That was even more exciting."

Stuart revealed his new project was under way when he was made a Member of the Order of Australia in June.

Now he's got his sights set on the next stage - the no small matter of raising $4 million.

A great run from Media Award, whose jockey Jack Martin just happened to be isolating in Canberra this week so he could ride the big race in Sydney, and he'll be a 10th of the way there.

Calthorpe's "bullish" about his $34 shot's chances, where I'm Thunderstruck's the $4 favourite.

It's a passion Stuart somehow finds the time to fit in in amongst his coaching duties and the numerous other causes he's happy to support.

He knows first hand the plight of a lot of disabled adults, who have been forced to live in aged-care facilities because of a lack of alternatives and he's trying to change that.

"The foundation secured a block of land through the generosity of Village Building Company at South Jerrabomberra," Stuart said.

"And we're now in the process of having to raise $4 million for the build.

"We're building a house with six bedrooms for young adults living with a disability, with full care and it's an independent style of living for these young adults.

"It's basically to try and assist the growing numbers of young disabled adults having to live in aged-care facilities."
