Ethereum Girl, a daughter of Maurice, has had two runs back from a break after winning at Stakes level in Adelaide in July.
She was a close-up fourth in the Thousand Guineas Prelude (1400m) at Sandown on September 27 before running eighth in the Thousand Guineas (1600m) at Caulfield on October 18.
Ben Hayes set the race set-up, that favoured those on-speed, did not suit Ethereum Girl last start.
"She was only second up into the Thousand Guineas and that race shape probably didn't suit her when they walked and sprinted home," Hayes said.
"She's stepping up to the 2000 (metres). She's third up now and we've always wanted to get her out in trip, so we're looking forward to seeing how she goes.
"She galloped here (Flemington) this morning. She was good, she had a good look around and just floated over the last 200 metres.
"If she's able to run well, or win, then we would definitely consider the Oaks."
