Ireland will fight with France for a place at the Tokyo Olympics Sevens after beating Hong Kong 28-5 in the semi-finals in qualifying in Monaco.
Jordan Conroy has scored two of Ireland’s four tries to bring his tournament touchdown to nine.
Two goals from Conroy and a try from Foster Horan helped Ireland lead 21-0 at halftime, with Harry McNulty adding a fourth before Liam Herbert’s late response.
Only the winners will qualify for the Tokyo Games.
The French were arguably even more impressive in their 31-0 semi-final victory over Samoa.
Earlier on Sunday, Ireland beat the Samoans 21-7 to top Pool A, which allowed them to avoid a semi-final clash with the quality French as Horan, Conroy and Jack Kelly were the Irish scorers.
Conroy is the tournament’s leading try scorer heading into Sunday night’s deciding game.
Ireland took three Pool A wins on Saturday as they beat Zimbabwe [31-10], Mexico [31-0] and Tonga [43-0] dominantly.
Terry Kennedy scored eight tries in Saturday’s three games – including two hat tricks – and he scored Conroy’s tries in Sunday’s first two games.
The Irish squad includes Ulster winger Aaron Sexton, who is a former Irish Schools 100m champion and still holds the schools national record for the sprint.
