“It is an opportunity for us as coaches to get the squad together ahead of the [2020] Six Nations and it will be a great day for all the fans.”
Jasmine Joyce and Elinor Snowsill started for Barbarians in their 40-14 defeat by England women at Twickenham last weekend and could face the invitation team in the autumn.
Alisha Butchers also played for Barbarians when they beat USA 34-33 in April, a game in which Joyce scored four tries.
Wales women’s coach Rowland Phillips said: “It has been a huge honour to have three current Wales players – Elinor Snowsill, Jazz Joyce and Alisha Butchers involved in the Barbarians’ first two international games.
“All three made an excellent contribution to the club.
“It’s also great to see two Welsh coaches involved – Liza Burgess in recent matches and now Rachel Taylor.”
The Barbarians are an invitational team which has been playing national sides on a regular basis since 1948.
The Barbarians women began life with wins over Munster and the British Army in 2017-18.
