Clarke flew out of Sydney for Australia's two-Test series in the West Indies, which will be followed by an England tour during which he will aim to lead the first Australian side to win the Ashes in England since 2001.
Clarke's men hold the urn after their 5-0 thrashing of England in Australia in 2013-14, a series during which Pietersen was England's leading scorer.
It also marks the last time Pietersen played for his country, and the newly-appointed England director of cricket, Andrew Strauss, last week effectively ruled out any return for Pietersen due to a "massive trust issue" between the two of them.
