Miss Agusta made a successful to flights when taking the opening maiden hurdle over an extended two miles in Ballybrit.
Gordon Elliott 's mare was uneasy in the market as she drifted from 5/6 to 11/8, however, she still retained favouritism.
She was runner-up in two of her five bumpers - in the valuable Goffs Land Rover Bumper at Punchestown in April last year and in a Listed mares' bumper at Fairyhouse in April this year.
The daughter of Well Chosen closed on 50/1 leader Saddle Her Up two out and, although she didn't put in her best jump there, she took a narrow lead approaching the last.
Jack Kennedy drove her home on the run-in by two and a-half lengths from the game runner-up. Notkeepinyagoing (7/2) finished well for third, a further half a length away.
Kennedy said: "We didn't go overly quick and she was a bit keen. She settled at times and then she started running with me the odd time, but I think she'd settle away the finest in a strongly-run race.
"She couldn't have done much more - I'm delighted with her as it is testing out there, but she went through it fine."
