Ireland manager Paul Earley has confirmed that Jarlath Fallon has joined the Ireland set-up as a selector ahead of the two-match series.
Fallon, who represented Ireland in the hybrid code in four Tests, joins Tony Scullion and Séamus McCarthy as part of the management team.
The former Galway star replaces Ciarán Whelan, who has stepped down from his role as selector citing other sporting and professional commitments.
In the aftermath of the appointment, Earley said: “I am very disappointed for Ciarán personally, as I know how much he was looking forward to working with some of the top players in the country.
“He has made a great contribution to date as part of the management team, particularly in the process we undertook to identifying players.
“I am delighted to welcome Jarlath on board as a selector and I know he will make a huge contribution to helping us to put the best possible team out on the field for our two games against Australia.”
Ireland play Australia on 19 October in Kingspan Breffni Park, before the second Test in Croke Park seven days later.
