He expects it will be like this for a while yet, but doesn’t mind in the slightest as he continues to celebrate his once-in-a-lifetime moment. 

Tobin, of Gwynneville, is a part-owner of She Will Reign – a $20,000 bargain filly which took out the $3.5 million Group 1 Longines Golden Slipper (1200m) at Rosehill.

Speaking to The Illawarra Mercury on Sunday, he still couldn’t believe his luck. 

“It was absolutely brilliant,” Tobin said.

“It was mind-numbing. It was just like you were on a pleasant, floating enjoyable high.

“It is life changing. The effect it has on you, your family and your friends.

“My phone has rung off it’s hook. I must have had 1000 texts in the last 24 hours. Facebook has gone gangbusters.”

Trained by Gary Portelli, She Will Reign was the cheapest filly in an elite field of juveniles for the richest two-year-old race in the world.

But by shortly after 4.15pm on Saturday afternoon that value had undoubtedly sky rocketed to make her one of the most expensive.

Jockey Ben Melham produced a stellar ride from a tricky gate to help She Will Reign ($8.50) race into the history books.

Melham barely went around a horse as he scooted along the fence heading into the straight before unleashing a devastating sprint on the heavy surface to beat Michael Freedman’s Frolic ($7.50), with the Hayes and Dabernig trained Tulip ($7.50) in third.

“When she started to move up I started to get confident,” Tobin said.

“When she moved up on the side of Houtzen, I thought she is going to go is going to take them here.

“It was a great ride.

“I said to Benny [Melham] when I shook hands with him and said that was a masterful ride.

“Gary Portelli actually wanted him to go wider and he said I think the fence in the best place.

“He said I am going to do what I did in the Silver Slipper.

“He stayed on the fence and took the short cuts.”

Tobin, who is a retired nurse that had previously owned three other horses, believes the sky is now the limit for She Will Reign

Darby Racing boss Scott Darby confirmed to Fairfax Media last week that he had interest from an investor that was looking for horse to target at the $10 The Everest later this year and had She Will Reign in mind. Owners pay $600,000 to get a spot in the field.
