Jason Collett will be picking his sister’s brain ahead of the Gr.1 Ranvet Stakes (2000m) on Saturday.

The Sydney-based expatriate Kiwi jockey will be aboard Alysha’s regular mount Consensus for trainer Stephen McKee in the Rosehill feature.

"She was my sister's first Group One so she'll tell me all about her," Collett said.

Consensus has won eight races, including the 2016 Gr.1 Zabeel Classic (2000m) at Ellerslie.
