Nagle will stand in for Mikkelsen’s usual co-driver, Mikko Markkula, who is recuperating after injuring two vertebrae at Rally Finland.
Mikkelsen had to withdraw from last week’s Rally Germany at the last minute, as Markkula’s injury was too severe to allow him to start.
Nagle and Mikkelsen have known each other since they went head to head at the Rally Ireland in 2007. Back then, Nagle was co-driver to Britain’s Kris Meeke.
“We are pleased to have found such a competent replacement so soon after Mikko’s withdrawal,” said Volkswagen Motorsport Director Jost Capito.
“Paul has a wealth of rallying experience and, with his professional approach, will definitely meet our expectations. We wish Mikko a speedy recovery. He can now take his time and concentrate fully on ensuring he gets back to full fitness. As soon as he has recovered from his injury, he will take his place next to Andreas again.”
“It is obviously a great shame that Mikko will also be missing for the Rally Australia. However, the good news is that we have found a good replacement,” added Mikkelsen.
“For me, it was important to find a co-driver, with whom I can communicate in English in the cockpit. Mikko and I changed the style of our pace notes ahead of this season, and both switched from our native language to English. It is an advantage for me not to have to change language again.”
Coates Hire Rally Australia is the tenth round of the 2013 FIA World Rally Championship and starts from Coffs Harbour on 12 September.
