World champion Australia completed a 5-0 whitewash over Pakistan with a clinical 20-run win in the fifth and final one-day international despite a brilliant hundred from Haris Sohail in Dubai Sunday.

Sohail scored a 129-ball 130 for his second one-day international hundred but failed to take Pakistan past Australia's imposing 327/7, finishing at 307/7 in 50 overs.

Australia's total was built around Usman Khawaja's 98 and a fiery 33-ball 70 by Glenn Maxwell coupled with Shaun Marsh's 61 and skipper Aaron Finch's 53 in a dominating batting show.  

The series win gives Australia an eighth straight one-day victory following their 3-2 series win in India after losing the first two matches.

It gives them a sixth successive series win over Pakistan since losing in 2002 (in Australia) and fourth whitewash over their opponents - 1998 (3-0 in Pakistan), 2010 (5-0 in Australia) and in 2014 (3-0 in United Arab Emirates).
