As of Thursday morning, Benagil was second in the line of betting at $5, with Mark Zahra taking the ride in the 2200m event.
The Roses winner Philia is set to jump as favourite at $4.20 but will have to overcome barrier 16 with Kerrin McEvoy on board.
With Benagil’s last three starts coming over 2000m, Thompson expected the extra distance to carry no dramas for the filly.
“I don’t think it’ll worry her, I guess it’s just a bit of the unknown - look she settles well, but I guess we’ll find out on Saturday,” Thompson said.
“Eagle Farm will suit her a lot better, it was always a bit of a concern going to Doomben, and I did toss up going straight from the Australasian Oaks to this Oaks but it was probably just a week too far.”
Saturday’s meeting will also see the running of fellow Group 1 races the Kingsford Smith Cup and the Queensland Derby following last weekend’s postponement.
