Colette and stablemate Avilius had an exhibition gallop between races at Rosehill on Saturday and Cummings is confident both are on target to feature this spring.
While Colette has showcased her staying capabilities, Cummings believes she has the speed to be competitive over shorter journeys.
“She has come back well,” Cummings said.
“She has a little bit of speed which you would like to see from a now four-year-old mare who has had a spell since her Oaks campaign.”
Everest favourite Nature Strip resumes in the Concorde Stakes (1000m) at Randwick while Surprise Baby, who heads Melbourne Cup markets, is scheduled to kick off in the Group Two Feehan Stakes (1600m) at The Valley.
Hawkes Racing will also continue the campaigns of some of their spring big guns.
Master Of Wine, prominent in Caulfield Cup and Metropolitan markets, is entered for the Feehan, while Epsom equal favourite Masked Crusader and Angel Of Truth are nominated for races at Randwick.
Horse travel between the two states became easier this week with Racing NSW easing restrictions to allow horses from Melbourne to enter NSW, provided they adhere to strict biosecurity protocols.
