July 6 (Reuters) - Australian shares were shaky on Thursday, with gains in healthcare and real-estate stocks offset by losses in the banking sector, after the Federal Reserve's policy minutes showed a lack of consensus on the future pace of interest rate increases.
The S&P/ASX 200 index dipped 0.1 percent or 2.7 points to 5,760.6 points by 0243 GMT.
Financial stocks were the biggest drag with the Big Four banks - Westpac, Commonwealth Bank of Australia , National Australia Bank and Australia New Zealand Banking - all drifting lower.
Minutes from the Fed's last policy meeting released on Wednesday showed policymakers increasingly split on the outlook for inflation and how it might affect the future pace of interest rate rises.
The details of the meeting, at which the U.S. central bank voted to raise interest rates, also showed that several officials wanted to announce a start to the process of reducing the Fed's large portfolio of Treasury bonds by the end of August but others wanted to wait until later in the year.
"All in all, the minutes essentially show that these officials do not seem to have a clear picture of where things are really heading, and what the appropriate policy calibration will be," OCBC Bank said in a note.
Market sentiment was also dented by oil prices which plummeted about 4 percent on Wednesday, ending their longest string of daily gains in more than five years, as rising OPEC exports and a stronger dollar spurred selling.
Among energy stocks, Beach Energy Ltd fell 1.3 percent while WorleyParsons Ltd was down 2.1 percent.
Meanwhile, the world No. 1 stand-alone wine company Treasury Wine Estates Ltd fell as much as 2.1 percent to touch a near two-month low.
Despite the losses on the benchmark during the day, advancing issues outnumbered declining ones by a 1.2-to-1 ratio.
Sentiment in some of the sectors was boosted by data showing Australia's trade surplus rebounded sharply in May as coal shipments recovered faster than expected from cyclone disruptions, putting exports back on track to add to economic growth in the quarter.
Among the gainers, biopharma giant CSL Ltd climbed 1.8 percent while retailer Wesfarmers was up 1.1 percent.
New Zealand's benchmark S&P/NZX 50 index edged 0.2 percent or 13.27 points higher to 7,608.94.
The utilities sector drove the index higher and accounted for more than one-fourth of the gains.
Contact Energy Ltd and Mercury NZ Ltd were among the big gainers in the sector, rising 1.5 percent and 1.3 percent, respectively.
