However, the investors are expected to assess the outcome of Australia's federal budget released on Tuesday. The share price index futures rose 0.08 percent or 5 points to 6,082, a 9.9-point discount to the underlying S&P/ASX 200 index close. The benchmark rose 0.4 percent on Tuesday. New Zealand's benchmark S&P/NZX 50 index rose 0.02 percent in early trade. (Reporting by Shanima A in Bengaluru)
