Sekope Kepu and Nic White are the latest Wallabies to announce they will leave Australian rugby after this year's World Cup.

Starting prop Kepu has signed a three-year deal to join French Top 14 club Bordeaux-Begles, who last month unveiled the key signing of Adam Ashley-Cooper on a similar deal.

White, meanwhile, will link up with French rivals Montpellier to be coached by his former Brumbies mentor Jake White on a two-year contract, with an option in his favour to extend it by another season.

Ashley-Cooper, Kepu's team-mate at the Super Rugby champion New South Wales, announced his intentions in December on the same day former skipper James Horwill signed off on his move to English side Harlequins.

Kepu, 28, has been capped 52 times by Australia and is sure to be a key figure in Michael Cheika's plans for the World Cup to be hosted by England later this year.

The 24-year-old White has made 19 Test appearances for the Wallabies.
