Hayden continued his recent one-day form

Maher's 60 included seven fours and three sixes in a 49-ball innings, setting Australia on their way to a total of 226 for seven.

A mini-collapse, saw Maher, captain Ricky Ponting, Damien Martyn and Darren Lehmann all dismissed in the space of 12 runs.

But Hayden and Michael Bevan put on an 87-run partnership, with the one-day specialist providing just 17 runs.

Nathan Hauritz, left out by Australia after making his debut in South Africa, produced his second stand-out performance with the ball in as many days.

The Queensland off-spinner finished with one for 17 off eight overs.

Bowling success

But Australia's current spin incumbent, Shane Warne, also starred, conceding just 19 runs from his eight overs, and capturing two wickets.

Glenn McGrath and Brett Lee also took braces as Queensland were retricted to 154 for eight, stand-in wicket-keeper Chris Hartley top-scoring with 34.

As on Saturday, the match, at Allan Border Field, took a relaxed approach to team selection.

Glove-man Wade Seccombe switched sides to cover for Gilchrist's absence.

And all-rounder Shane Watson turned out for the state of his birth, having moved to Tasmania a year ago to make his mark in the first-class game.

Australia open the three-match series against Pakistan at Colonial Stadium in Melbourne on Wednesday.

The second match will be played at the same venue on Saturday with the third game at the Gabba in Brisbane on June 19.
