After recording her first win in the Group 2 Edward Manifold Stakes (1600m), Getta Good Feeling ran third in the Group 1 Thousand Guineas (1600m) and won the Group 2 Wakeful Stakes (2000m) before failing to run out the Oaks distance, when sixth behind Strictly Business.
For that reason, O'Brien did not even nominate Getta Good Feeling for the Group 1 ATC Australian Oaks (2400m) in Sydney and she also will not contest the key lead-up to that race, the Group 1 Vinery Stud Stakes (2000m), for which she is second favourite.
The $1 million Group 1 Australasian Oaks (2000m) at Morphettville on April 25 is what her campaign has been geared around.
"After Saturday, she'll then go probably three weeks and run over a mile (at Caulfield) at what was the old Moonee Valley meeting in the three-year-old fillies mile," O'Brien said, referring to the $200,000 Group 3 Alexandra Stakes (1600m).
"We'll just space her runs through to the Australasian Oaks.
"There's an option to go to Brisbane after that. The Oaks in Brisbane is 2200 and we just thought the 2500 in the spring found her out for stamina late."
