In 1994, Ramanayake reached the peak of her shooting career by landing successfully to fifth place in her pet event at the Asian Games in Hiroshima, Japan with 488.7 points. Ramanayake's rise continued on that same season, when she and her fellow markswoman Malini Wickramasinghe won Sri Lanka's first ever gold medal in the air rifle pairs at the Commonwealth Games in Victoria, British Columbia.
