Rulach attended the St. Mary’s College, Dehiwala for his primary and secondary education.
[1] Rulach toured Australia along with the National School Cricket Association team in 1964.
He made his List A debut on 6 February 1974 playing for Sri Lanka against India in the second limited over match as part of the unofficial two match limited overs series which was played at Colombo Cricket Club Ground.
[4] He also thus missed an opportunity to play for Sri Lanka at the international level (the only exceptional case, he managed to play for Sri Lanka was in an unofficial List A match against India) due to failing to meet the criteria of studying at a more established school, as it was considered a benchmark for budding cricketers to be in the frame for selections to break into the Sri Lanka national cricket team.
[1][9][10] Sri Lanka Cricket posted a condolence message on their X account and instructed members of the Sri Lanka men's national cricket team to wear black armbands prior to the start of fourth day's play as part of the first test match of the series against Australia.
