Golden Slipper favourite Vancouver has drawn a wide barrier for the $3.5 million race.

Unbeaten in three starts, Vancouver drew barrier 18 and will start one stall from the outside alley if the three emergencies don't get a start.

"I never worry about barriers, everyone knows that. There's nothing you can do about them," trainer Gai Waterhouse said.

Three of Godolphin's runners have drawn single-digit gates with Furnaces to start from the rails.

Exosphere, rated the top pick among Sheikh Mohammed's quartet, has drawn the widest in gate 10.

Stablemates Haptic and Ottoman have drawn barriers three and eight respectively.

Vancouver's stablemate English has barrier six while the outsider of Waterhouse's trio, Saturday's winner Speak Fondly, has gate 12.

Waterhouse is chasing a record-equalling sixth Golden Slipper win.

Hawkes Racing will have two runners with Headwater to start from 11 and the Blue Diamond Stakes placegetter Lake Geneva in gate five.

There are seven colts and 12 fillies among the final 19 acceptors for the world's richest race for two-year-olds at Rosehill on Saturday.
