June 5 (Reuters) -Australian shares inched higher on Wednesday, as gains in banks and healthcare stocks outweighed losses in commodity-related sectors, while investors awaited March-quarter economic growth data due later in the day for further direction.

The S&P/ASX 200 index .AXJO rose 0.2% to 7,750.7 by 0030 GMT. The benchmark fell 0.3% on Tuesday.

The gross domestic product (GDP) data due at 0130 GMT is likely to show a growth of 0.2%, according to a Reuters poll.

Data released on Tuesday showed Australia's current account unexpectedly swung into deficit in the March quarter as imports jumped and prices for commodity exports fell, possibly taking a chunk out of the GDP.

Gains at the bourse were led by healthcare firms .AXHJ, with the sub-index rising 1.1% to its highest in three weeks. The real estate sub-index .AXRE climbed 1.6%.

Rate-sensitive financials .AXFJ rose 0.5%, with the "Big Four" banks up between 0.3% and 0.7%.

Bucking the trend, miners .AXMM on the resources-heavy bourse dipped 1.4%, nearing a one-month low. Sector behemoths BHP BHP.AX, Rio Tinto RIO.AX, and Fortescue FMG.AX were trading lower by 1.1%, 1.2%, and 0.7% respectively
