The England and Wales Cricket Board (ECB) said on Friday that Broad, who took a creditable 21 wickets in the five tests, will sit out the matches in Melbourne and Brisbane.
Broad will be available for the final three ODIs and will captain England in three Twenty20 internationals.
With Graeme Swann retired and James Anderson having flown home, Broad's absence from the first two of five one-dayers
means England will field an inexperienced bowling attack.
Seamers Tim Bresnan, Steven Finn and Warwickshire all-rounder Chris Woakes are the most experienced replacements set to fill-in for Broad.
