Australia A require another five wickets for victory after setting Sri Lanka A 424 to win the opening first-class game of the series in Brisbane. South Australia's Peter George collected all five breakthroughs as the visitors pushed to 5 for 224 at stumps on day three.
The opener Tharanga Paranavitana started well with 47 and Dinesh Chandimal made 54 and Kaushal Silva collected 47, but George was a constant threat and returned 5 for 55. Batting was easier than on the first two days, but Australia A will look to wrap up the match quickly on the final morning.
George Bailey, the captain, posted a game-high 87 as Australia A added 118 to their overnight total of 4 for 110. The innings seemed to be close to an end when Steve O'Keefe added 47 - it went with his 61 on Friday and his 7 for 35 yesterday - and Bailey was dismissed to give Sachithra Senanayake his 11th wicket of the game.
However, Ben Hilfenhaus raced to his maiden first-class half-century, striking six fours and two sixes, to take the lead past 400. Senanayake finished with 3 for 110 to go with his 8 for 70 in the first innings, while Dammika Prasad also collected three breakthroughs.
