Australia have only played Bangladesh in two ODI's since 2011. The 2015 World Cup clash in Brisbane was washed out without a ball being ball while the Champions Trophy clash in 2017 ended without a result with rain halting Australia's chase.
Bangladesh included Rubel Hossain and Sabbir Rahman in this match as Mohammad Saifuddin and Mosaddek Hossain Saikat were left out due to injuries.
Saifuddin has been suffering from a back problem while Mosaddek sustained a blow on his right shoulder in the previous game against West Indies.
Before heading to this match, Australia played five matches and won four of them. Their only setback came against India. The defending champions are now at number three in the points table.
Bangladesh, on the other hand, played five matches so far as well and won two of them. They suffered two losses against New Zealand and England with the other match against Sri Lanka was washed out due to rain.
