July 14 (Reuters) - Australian shares posted broadbased gains for a second straight session on Friday, and were on track for their best weekly performance in a month, as financials tracked their Wall Street counterparts higher ahead of big U.S. banks earnings.
The S&P/ASX 200 index was 0.5 percent, or 27.37 points, higher at 5,763.70 by 0235 GMT after a 1.1 percent rise on Thursday. The benchmark has added over 1 percent so far this week, heading toward its strongest weekly rise since the week ended June 16.
The day's gains rode on a solid rise in energy and financial stocks, with the Australian energy index on track to record its best trading day since early May with a 2.4 percent rise.
Aussie energy sector bellwether Woodside Petroleum, an oil and gas explorer, climbed 2.1 percent boosted by overnight advances in oil prices, which came on the back of data showing stronger Chinese demand for crude.
Smaller rivals Oil Search and Santos rose about 1.7 percent each.
Origin Energy, which has significant natural gas interests, was also helped by the rise in oil, gaining 2.7 percent and thereby single-handedly pushing up the utilities sector.
The Australian financial index followed U.S. financials higher as investors bought in before second quarter earnings kicked-off with three of the biggest U.S. banks reporting results.
"Our markets are looking ahead to the reporting (earnings)from the U.S. with a degree of optimism," said Tony Farnham, an economist with Patersons Securities.
A Reuters survey showed second-quarter earnings for S&P 500 companies rose 7.8 percent from a year ago, with financials projected to have had the third-best profit growth among sectors.
The Aussie big banks rose in a range of 0.7 percent to 1.2 percent and were the biggest contributors to overall gains.
Meanwhile, the second leg of U.S. Federal Reserve chief Janet Yellen's testimony, this time before a Senate panel, further buttressed her advocacy of a gradual rate of policy tightening.
Investors have seen Yellen's dovish tone as a green light for riskier trades on Wall Street.
New Zealand's benchmark S&P/NZX 50 index added 0.3 percent or 23.24 points to 7,634.13, and was on track for a fifth straight week of increases.
Gains were concentrated in consumer, utilities and financial shares with dairy products maker a2 Milk and energy retail business Mercury NZ Ltd the biggest advancers on the benchmark, up 1.5 percent and 3.3 percent, respectively.
