After winning a good toss under overcast conditions, Australia decided to test its batting might by taking first strike in a match already shortened to 34-overs-a-side because of bad weather.
It lost David Warner to Mohammad Amir in the fifth over, but Aaron Finch and Steven Smith carried it to 57 for 1 before rain forced the abandonment.
Finch was in particularly fine touch, reaching 36 from as many balls with seven fours - three of which came in a row in a Fahim Ashraf over.
Australia and Pakistan were both involved in close clashes in their opening warm-ups against Sri Lanka and Bangladesh respectively before ending on the right side of the result, and would have liked some game time in what was their last warm-up fixture before the tournament begins.
Australia, the two-time champion, kick-start its Group A campaign with a game against New Zealand here on June 2 before facing Bangladesh (The Oval, June 5) and England (Edgbaston, June 10).
