The Welsh sevens squad was disbanded by the Welsh Rugby Union (WRU) due to financial constraints. After a three-year absence, the Wales sevens team returned to international competition in the 2006–07 season. They competed at half of the eight tournaments and won the plate competition (fifth place) at each of them. They repeated this feat at the 2006 Commonwealth Games.
In Wales's first ever cup final appearance in a major rugby sevens event, Wales played Argentina in the 2009 World Cup Final.
In the Group stages Wales beat Zimbabwe 31–5 and Uruguay 27–0 before losing to Argentina 14–0 in the final pool match, leaving Wales uncertain of a cup quarterfinals spot. With results going their way Wales made it to the cup quarterfinals as one of the second place qualifiers for the first time in their history.
Wales beat favourites New Zealand in the quarterfinals 15–14, and defeated Samoa in the semifinals 19–12.
Wales faced Argentina for the second time in the tournament in the Final. Wales started with the same team that played against New Zealand and Samoa earlier in the day. At half time Wales had a lead of 12–7 after tries from Richie Pugh and Tal Selley.
In the second half Argentina levelled the score at 12–12. With less than 90 seconds left, Wales's Aled Thomas scored underneath the posts and with a successful conversion put Wales into the lead at 19–12.
Argentina claimed the restart. After the siren sounded to indicate there was no time left on the clock Argentina fumbled the ball in a ruck leading to the ball being kicked out of play and Wales being crowned the 2009 Sevens Rugby World Cup Champions.
