Johnson, a major target for Wallabies coach Eddie Jones' support team, will work alongside new Wales supremo Mike Ruddock.

Skills specialist Johnson has spent the last two years in Wales, receiving widespread acclaim for his work with an outstanding Welsh back division.

And having just returned from Australia - he spent time Down Under for family reasons - he is relishing the task ahead.

"I'm back, and it is business as usual from here on in,'' said Johnson.

"I can't wait to get back to talking about rugby and working hard with the squad, and I am looking forward to establishing a strong working relationship with Mike.''

Both Johnson and fitness coach Andrew Hore, who has also committed his future to Wales, will be involved in this summer's demanding tour of Argentina and South Africa.

Ruddock expects to make a further announcement next week, as the position of defence coach is still to be filled within his management set-up. Former Wales rugby league chief Clive Griffiths is favourite for that post.

"Scott and Andrew have done a great job and achieved a lot over the last two years, and I will hopefully be able to bring some of my own experiences into the set-up now and enhance the team's performance,'' said Ruddock.

"We are also just a week or so away from appointing our defence coach, who will be the final piece in the jigsaw and a key member of the team.''

Ruddock's first match in charge is against the Barbarians at Ashton Gate on May 26, before Wales face Argentina (twice) and South Africa during three successive June weekends.
