In January 2016, Bealham was called up to Ireland's squad for the Six Nations to replace the injured Marty Moore. After Cian Healy injured his hamstring, Bealham was promoted to the bench for the game against Italy. On 12 March 2016, 65 minutes into the game, he replaced Jack McGrath for his debut. Bealham was named in the Irish squad for the team's 2016 tour to South Africa, where he was named on the bench for all three tests, coming on as a 59th minute replacement for Tadhg Furlong in the second.
