A day after securing a $2.3 million sibling to this season's likely Horse of the Year, Gai Waterhouse has paid top price at the second session of the Easter sale for the brother of a previous champion.

The half-brother to Winx sold on Tuesday will be joined in the Waterhouse stable by Lankan Rupee's younger brother who fetched $1.8 million.

By Redoute's Choice out of Estelle Collection, the colt will race for an ownership group put together by Waterhouse and Julian Blaxland.

"He's got the (pedigree) page. He's got the physique and with Redoute's Choice getting on, his best colts are now rare jewels," Waterhouse said.

"I'm very privileged to be training a colt like this for such a group of investors. He looks a precocious sort as well and it's very exciting to get him.

"There are some new owners which is great.

"There is some international investment in him and as a brother to a champion he really is a case of the creme de la creme."

Gerald Ryan will go home with the next two top lots of the day - a colt by Snitzel out of Family Breakup and a Fastnet Rock filly out of Hips Don't Lie, both knocked down for $1.1 million.

"I think the colt was the best Snitzel in the sale," Ryan said.

"He is very athletic and will never get heavy. I think he can be an autumn two-year-old."

Ryan trained Group One winner Snitzel and has an affinity with his progeny.

The first three yearlings by unbeaten European champion Frankel offered in Australia met with mixed results.

The first of the three failed to reach his $500,000 reserve by $25,000 but the next two were snapped up.

Sheikh Hamdan's bloodstock adviser Angus Gold paid $610,000 for a filly out of Chocolicious, but admitted he didn't expect to pay such a premium.

"To be honest, I didn't think we'd have to pay that," Gold said.

"But she looks much more precocious than any Frankel I've seen. She looks like she should be a two-year-old."

Gold said he had seen a lot of Frankel's progeny overseas, but nothing had taken his fancy until he came to Sydney.

"I love the attitude of this filly," he said.

"I went into the box beforehand to see her and it's a no-nonsense hardy looking thing that wants to get on with it."

The filly will do her racing in South Africa.

Katsumi Yoshida of Japan's Northern Farm paid the top price for a Frankel yearling of $750,000 for a colt out of Jeu De Cartes.

Two more Frankel yearlings will be offered on the final day from mares sent to him in England to be bred to southern hemisphere time.
