The game at Bristol’s Ashton Gate on Sunday 14 September will be a sell-out and will determine which team takes up the fourth and final spot in the semi-finals.
France’s Aurélie Groizeleau will referee the game, and she will have Italy’s Clara Munarini as her No 1 assistant referee and Stamp-Dunstan as her No 2 on the other touchline.
England’s Sara Cox will control the first quarter final between New Zealand and South Africa at Exeter’s Sandy Park on Saturday, while Scotland’s Hollie Davidson will be in the middle for the second game at Ashton Gate later in the same day when Canada meet Australia.
The game between France and Ireland at Sandy Park on Sunday will be refereed by South Africa’s Aimee Barrett-Theron.
Although born in Gloucestershire, to a Welsh mother and English father, Stamp-Dunstan, who turns 24 later this month, is a product of the Welsh refereeing system.
She started her rugby journey as a player at the age of six at Lydney RFC but was forced to give up at the age of 16 after suffering repeated shoulder dislocations while playing in the back row for Drybrook RFC.
That’s when she first attended a two-day ‘Ready to Ref’ course organised by the Welsh Rugby Union in 2019. She started refereeing girls' U15 games and progressed to senior women’s rugby, along with male youth and senior rugby, as a member of the Gwent Referees’ Society.
The former Monmouthshire Comprehensive pupil, who has been studying sport management at Cardiff Met, then made history early in the 2023/24 season when she, along with another female referee, became the first women to referee in the men’s WRU Admiral Championship.
