SYDNEY, June 4 (Xinhua) -- The Australian share market opened higher on Tuesday, thanks to a surge in materials, and most other sectors were trading flat ahead of an expected lowering of interest rates by the central bank later in the day.
At 10:30 (AEST), the benchmark S&P/ASX 200 index was up 15.20 points or 0.24 percent at 6,335.70, while the broader All Ordinaries index was up 13.10 points or 0.20 percent at 6,423.90.
Locally, tech stocks plunged and materials surged, while most other sectors were trading close to flat.
"The relatively benign overnight trading has Australian traders focussed on April retail sales data due this morning and a potential interest rate cut from the RBA this afternoon," CMC Markets chief market strategist Michael McCarthy said.
"There is almost universal agreement that among economists that Governor Lowe will announce a 0.25 percent cut in the cash rate."
