Aaron Finch's men when they flick the switch to tournament mode this week. An underdone Australia gelled superbly during last year's triumph in the United Arab Emirates and 14 of that 15-man squad will bid for back-to-back titles on home pitches over the next few weeks. Since blanking twice champions West Indies at the start of the month, Australia have lost two warm-up matches to England and another against India in Brisbane on Monday as selectors tinker and players are rested. Finch made a welcome return to form with a half-century against India, though, and Australia had another burden lifted on Tuesday when Pat Cummins was confirmed as captain of the one-day side, an issue that threatened to become a distraction through the tournament.
