Australian shares extended their rally to a fourth session on Monday, hovering around 10-year highs as investors drew confidence from Wall Street after it capped off a strong week.

In Sydney, the S&P/ASX 200 index (xjo) advanced 0.3 percent or 17.5 points by 2350 GMT. The benchmark rose 0.7 percent on Friday.

Financials accounted for nearly half the gains on the index, with Commonwealth Bank of Australia (CBA) rising 0.7 percent to a near five-month peak.

Other banks in the "Big Four" notched gains of between 0.4 percent and 0.8 percent.

Healthcare stocks were also sought out in early trade, with CSL Ltd (CSL) and Cochlear Ltd (COH) climbing 0.9 percent and 2.4 percent, respectively.

Real estate investment trust DEXUS Property Group (DXS) was among the top gainers on the index, up 1.8 percent to a near three-week high.

"People are willing to buy today, but I think there's some caution creeping in because the market has had a strong run", said Christopher Conway, head of research and trading at Australian Stock Report.

Conway suspects the Wall Street-backed rally, which is common during late-December to early-January, will slow down as more people return from their holiday breaks.

Insurer Suncorp Group (SUN) limited the market's upside, slipping 1.4 percent to an over two-month low after it flagged a A$160 million - A$170 million ($125.73 million - $133.59 million) hit to its half-year earnings due to a hailstorm that pelted Melbourne in December.

Commodity prices lost steam after a recent strong rally and pressured miners. Australia said it expects iron ore prices to average $51.50 a tonne this year, down 20 percent from 2017, because of rising global supply and moderating demand from top importer China as its steel sector shrinks.
