Snyman was named in South Africa's squad for the 2019 Rugby World Cup. He played all 7 games, mainly off the bench, and scored his first test try against Italy. South Africa won the tournament, defeating England in the final. Despite an injury-disrupted 2020–21 season and burns sustained during a firepit accident, Snyman was selected by head coach Jacques Nienaber in South Africa's squad for the 2021 British &amp; Irish Lions tour to South Africa, however, the aforementioned burns required a skin graft, ruling Snyman out of the series. He initially returned to Munster for his rehabilitation, but rejoined the South Africa squad for the 2021 Rugby Championship.
