Munster coach Alan Gaffney will leave Ireland at the end of this season to take up a new post as assistant coach to Eddie Jones' Wallabies.
Speaking about the impending departure, Munster Chief Executive Garrett Fitzgerald said: "We had hoped that Alan would extend his contract with us for a further period.
"His three years here has been hugely beneficial and we do of course regret losing a coach of his ability, one who has served Munster rugby so well.
“However we fully understand his decision to accept the offer from the Australian Rugby Union. It is a tremendous honour for him and we wish him the very best of luck in his new role".
Gaffney admitted: “It was tough. These are a great bunch of guys. I have had three marvellous years with Munster and enjoyed every minute.
"Munster have been good for me and for my family. I have had a very good working relationship with all concerned, particularly Garrett Fitzgerald (CEO) and Jerry Holland".
Connacht coach Michael Bradley will be odds-on to become the new Munster head coach.
