Bouncing back into reckoning with a win over India, Sri Lanka will face a tough test when they take on world champions Australia in a cricket tri-series one-dayer here tomorrow.The much-needed eight-wicket victory against India in a rain-truncated game in Canberra on Tuesday has served as a tonic for the islanders who will now look to consolidate their position by putting it across the hosts at the WACA.The weather has really played spoilsport in the series so far with two matches being abandoned and one affected by rain but the met office has predicted a sunny day tomorrow, providing the perfect setting for what promises to be an absorbing contest between two talented teams.The Australians, however, will have a distinct advantage as the visitors will have to quickly come to terms with the pacy track at the WACA where India recorded one of their greatest overseas Test triumphs nearly a month ago. The Indians are currently on top of the points table with eight points from four matches while Australia were just one point behind them from three matches. Sri Lanka are at the bottom of the table with seven points from three games.As per the tournament format, all the three teams will play against each other four times before the two top teams qualify for the best-of-three finals.
