Australia 2 for 142 (Warner 67, Watson 62*) beat West Indies 7 for 138 (Deonarine 36*, Harris 2-27) by eight wickets
David Warner scorched the second fastest international half century in Twenty20's short history as Australia completed their unbeaten summer with a bang at the SCG on Tuesday.
In reply to the West Indies' 138 for 7, the home side reached the target with eight wickets and 50 balls to spare. Warner (67 off 29 balls with seven sixes) and Shane Watson (62no off 33 balls) caned the touring side's attack.
India's Yuvraj Singh holds the record for the fastest Twenty20 half-century from 12 balls against England in South Africa in 2007.
There was some drama in Warner's innings with the left-hander warned by the umpire for taking strike as a right hander as spinner Narsingh Deonarine came in to bowl.
The debutants Ryan Harris and Christian grabbed two early wickets each and Steven Smith was everywhere in the field, producing one of the most memorable catches of the summer. The trouble started when Chris Gayle tried to flick Harris over square leg and top-edged to Smith at third man for 12.
Another record for Australia, they completed a successful home season without suffering a single defeat in international cricket.
They played 19 games comprising six tests, ten ODIs and three T20Is against West Indies and Pakistan.
They emerged victorious in as many as 17 matches, drew a test and were involved in a no result ODI versus Windies for a magnificent winning ratio of 89.47.
Following are details of countries remaining unbeaten in the entire season at home in all internationals matches, arranged in the order of most number of wins:
