He's the son of the late Scotland international, Greig Oliver.
Oliver was born in Melrose but grew up in Ireland and has represented his adopted country at age-grade level.
He played for the Garryowen club in Limerick. He was added to Munster's Champions Cup squad in December 2021 and was a try-scorer on his first Munster start in the pre-season clash against Gloucester in September 2024.
However, first-team opportunities have been limited and he now looks poised to move to Glasgow for next season. This could also see him switch allegiance to Scotland.
