David Warner hit 166 when Australia hit a gigantic 381-5 beating first.
Australia returned to the top of the Cricket World Cup after beating Bangladesh for 48 races at Trent Bridge on Thursday (New Zealand time Friday).
Bangladesh's persecution of the Australian mammoth 381-6 was lively, but they ended up falling short of expectations, finishing at 333-8 of their 50 awards.
Mushfiqur Rahim scored an invincible (102 of 97 balls) in his reply, which was his biggest total in the international one day.

Earlier, David Warner scored 166 when Australia scored 381-5 against Bangladesh in Nottingham.
The innings were brilliantly inspired by Warner, who participated in a partnership of 121 with Captain Aaron Finch, then 192 with Usman Khawaja.
Australia became the first team to achieve partnerships of two centuries for the first two wickets in a World Cup.
Warner reached his second century of this World Cup with 110 balls, eight days after 107 against Pakistan in Taunton.
He did not overtake the ball race until day 41, when he and Khawaja began to accelerate. He became only the second man to hit more than 150 centuries in the history of the World Cup, and was playing a slower ball for the third man.
Warner's 166 came from 147 balls and included 14 limits and five six.
Finch was out for 53 and Khawaja made a 72-ball 89 after running out Glenn Maxwell for 32 out of 10 balls. Maxwell looked frustrated with Queenslander when he stopped on the field and drove away.
Finch, Warner, and Khawaja were all dismissed by midfielder Soumya Sarkar for short, short balls. They were the second, third and fourth wickets of Soumya's five-year ODI career.
Bangladesh equaled its own record of 50 awards when it chased 322 in 41.3 titles to beat the West Indies on Monday in Taunton.
While Australia is back on a wholly suitable roster, Bangladesh was forced to make two changes, including the loss of Wicket leader Mohammad Saifuddin for a back spasm. Saifuddin has nine wickets, including Chris Gayle, in the win over the West Indies on Monday.
Rubel Hossain arrived, while midfielder Mosaddek Hossain, who also wore two wickets at the World Cup, injured one shoulder and was replaced by Sabbir Rahman. Rubel and Sabbir will make their first matches in this World Cup.
Australia made three changes. Allrounder Marcus Stoinis and fast Nathan Coulter-Nile are recovering from bruises and replaced Shaun Marsh and Jason Behrendorff from the victory over Sri Lanka last Saturday and defender Adam Zampa is on the field for Kane Richardson. Stoinis and Coulter-Nile will play Bangladesh for the first time.
Australia want to consolidate their place in the semifinals, while Bangladesh is trying to enter. Both are coming out good wins. Australia eliminated Sri Lanka for 87 races last Saturday, while Bangladesh drove the West Indies down seven wickets on Monday.
Bangladesh beat Australia only once in 2005 in Cardiff. Captain Mashrafe Mortaza is the only survivor on both sides.
Australia's belief that the clashes in Bangladesh will not make money in Australia means that the teams are only playing their second international one day in eight years. Almost half of Australia's national team has never played in Bangladesh.
Australia easily won the previous World Cup clashes in 1999 and 2007.
