Strauss, successful against the Aussies in 2005, 2009 and 2010/11 - as captain on the last two occasions - has joined Sky's commentary team for the Ashes at home this summer and Down Under next winter.
The 36-year-old played in 100 Tests before retiring at the end of last summer.
Strauss said: "I am delighted to be joining the Sky Sports team for the Ashes.
"I can't wait to watch and commentate on what promises to be two exciting contests.
"I look forward to joining the guys in the summer and sharing my thoughts with the viewers."
