Among So You Are's runs for Osland was a second placing to now-stablemate Thebudgiesmugla in the Listed Caloundra Cup (2400m), a race that features in the form of the past two Melbourne Cup winners, Knight's Choice and Half Yours.
So You Are is the only runner from this year's Caloundra Cup engaged in Tuesday's big race.
He came up with barrier seven at Saturday night's barrier draw, which Ramsay said pleased his trainer and jockey, Rachel King.
"He wanted four to seven, I wanted two, but two had already gone," Ramsay said.
"There were only five and seven to go when he was draw out and I got one of them so all good.
"He might get beat, but I tell you what, he'll be there for a long, long way and it's just wonderful to have a starter."
So You Are is one of four horses in this year's Melbourne Cup who were bred in Australia, along with Knight's Choice, Strictly Business and Zakouma.
Viewed (23008), Shocking (2009) and Vow And Declare (2019) were the only Australian-bred winners of the race in the first 24 editions this century but Australian breeders are chasing a hat-trick of wins following victories to Knight's Choice and Half Yours.
