All 'Big Four' banks rose, with top lender Commonwealth Bank of Australia adding 0.5 percent.
Overnight, spot iron ore prices fell for a fourth straight day to a 20-month low, pressured by weak buying interest from china, the world's top consumer of the steelmaking raw material.
Meanwhile heavyweight miners Rio Tinto Ltd and BHP Billiton Ltd added 0.4 percent and 1.2 percent each, recovering modestly after being sold off over the past week. Investors will also eye the Chinese HSBC flash manufacturing PMI for May due at 0145 GMT.
"If the PMI number is outside of expectations significantly it will affect the big three, Rio, BHP, Fortescue", said Shawn Hickman, managing director at Market Matters
"The market is a bit 50/50, so we just want to see it play its hand, the whole region is up around 0.4 percent, there's not a great deal at the moment."
Energy stocks also rose, underpinned by U.S. oil reaching a one-month high overnight. Woodside Petroleum Ltd climbed 2 percent, while Santos Ltd added 1.1 percent.
Australia's benchmark index has been drifting sideways in May, pulled down by top-tier banking stocks with investors booking profits as shares have reached record highs, but underpinned by robust earnings.

New Zealand's benchmark NZX 50 index edged up 0.4 percent to 5,130.25, as gains in transport company Freightways and Fisher & Paykel Healthcare helped the index to recover from a one-month low hit on Wednesday.

Shares in telecommunications network operations Chorus Ltd tumbled roughly 4 percent after the industry regulator said it would delay a final decision on broadband pricing.
"(The delay) pushes out the time frame of the pricing issue possibly being resolved. It has added uncertainty ... and that would be seen as negative," said Michael Milne, investment advisor at Craigs Investment Partners.
But Milne added that the delay would give the company the opportunity to offer more input into the pricing process, which could be beneficial in the longer term.
