Bennett half-century as Zimbabwe make 169-2 against Australia
A 70-run stand between Bennett and Ryan Burl (35) held Zimbabwe's innings together after they were put in to bat by stand-in Australia skipper Travis Head.
The stand is a record for Zimbabwe for the second wicket in T20 World Cups.
Bennett's 56-ball knock contained seven fours and was a solid exhibition of skilful batting rather than power-hitting.
It was the tenth half-century in T20Is for the 22-year-old and he was ably assisted by fellow opener Tadiwanashe Marumani (35).
Zimbabwe thrashed Oman in their opener.
