Despite efforts of medical and emergency staff, Targa Australia confirmed the driver Leigh Mundy, 68, from Hobart, and co-driver Dennis Neagle, 59, from Withcott, Queensland, died at the scene.
Mr Navin’s co-driver Glenn Evans was not injured in yesterday’s crash.
“This has been a devastating few days for the Targa family,” Targa Australia CEO, Mark Perry said.
“Today our thoughts and deepest condolences go to Leigh and Dennis’ family and friends.
“Both loved Targa and we knew them so well, which makes their passing so difficult for everyone in our community.
“They will be sorely missed by us all.”
Today was the final day of the Targa Tasmania race.
Targa Australia said after today’s accident, the stages were downgraded “to touring only and competitors returned to the finish at PW1 in Hobart”.
The next of kin have been notified of today’s tragic events.
A report will now be made by the coroner.
