Danila competed only in the women's 100 m backstroke at the 2000 Summer Olympics in Sydney. She achieved a FINA B-cut of 1:06.19 after winning a silver medal from the Southeast Asian Games in Bandar Seri Begawan, Brunei. Swimming in heat one, Danila, who just turned 18 on the second day of the Games, gave the Filipinos a further reason to celebrate, as she overhauled a 1:07 barrier and rocketed to a fantastic first-place finish in a sterling time of 1:06.48. Danila's blistering triumph was not worthy enough to put her through to the semifinals, as she placed thirty-seventh overall out of 47 swimmers in the prelims.
