Australia thus surpassed India's 413/5 to record the highest team total in a World Cup match.
Courtesy Warner's career-best 133-ball knock and an attractive 95 off 98 balls from Steven Smith, Australia piled up runs with ease as the duo stitched a record 260 runs for the second wicket partnership.
While Warner's fourth ODI hundred was studded with 19 boundaries and five sixes, Smith's innings had eight boundaries and a six.
Maxwell hit six boundaries and seven sixes in his brief innings which was high on entertainment quotient.
