Clarke, appearing for Cricket Australia Invitational XI bowled two overs of left-arm spin after the visitors batted first at the Allan Border Field and fielded in the slips most of the time.
Clarke, who is recovering from a hamstring injury, also took a sharp catch off Ashton Turner to underline his sure hands in that position. In all, he fielded for 32 of the allotted 50 overs.
With coach Darren Lehmann watching him, Clarke managed to score 34 off 36 balls in a 47-minute innings. He punched six boundaries, before a leg-break from Sabbir Rahman took a thin outside edge.
Clarke though avoided running at top pace during the pre-World Cup practice fixture as he was able to do most of his work by jogging in the field or between the wickets. However his willingness to bowl may be seen as significant by selector Rodney Marsh, Lehmann and others.

"I've been bowling for the last three weeks in the nets, so the skipper needed a couple of overs so he asked if I was happy to bowl and I was certainly happy to," Clarke said.
"In my opinion I think there's probably still a gap between where I am now and playing an ODI for Australia, but fortunate thing is I have plenty of time to close that gap."
Clarke will be in Adelaide tomorrow as the Australian squad will assemble there and will continue to train though he will not play in the warm-up fixture against India on Sunday. He has a greater chance of appearing in the next practice fixture against the UAE at the MCG next week.
