Glen Ella will work with the England squad during their tour of Australia next month, as head coach Eddie Jones attempts to improve his side's attack.
Ella, who played club rugby for Randwick alongside Jones before working as part of his backroom staff at the 2003 Rugby World Cup, will join up with the squad in Brisbane.
He will work with England for the duration of the three-Test series, acting as skills coach, providing specialist backs coaching while being "responsible for helping develop England's attack play".
"I'm delighted to be teaming up with Eddie again and working alongside the rest of the coaching staff," said Ella.
"Eddie's got England moving in the right direction, but there's still a lot of work to be done, particularly in attack.
"I'm looking forward to being involved in an exciting series of Test rugby."
Jones added: "We're very happy that Glen will be joining up with us out in Australia.
"Glen has coached rugby all around the world and not only brings with him a wealth of experience, but also has one of the best attacking minds in the business.
"Working alongside myself and the rest of the coaching team Glen will assist me in developing our attack play strategies and also provide some specialist backs skills coaching.
"It's an area we know we need to improve and I'm sure we'll benefit greatly from having Glen on board for the tour."
