Australian shares extended the previous session's losses on Thursday as basic materials and energy stocks remained under pressure while investors cautiously navigated a flood of economic data from home and abroad.

The S&P/ASX 200 index (xjo) fell 12.93 points, or 0.24 percent, to 5420 by 0330 GMT, its lowest since mid-July. Australian shares finished at their lowest in more than six weeks on Wednesday.

Official data from China, Australia's biggest trade partner, showed manufacturing sector activity picked up unexpectedly in August. The gains were modest though, pointing to a steadying yet sluggish economy.

The energy index .AXEJ hit its lowest in four weeks on weaker crude oil features, with Woodside Petroleum (WPL) shedding 1.6 percent and Santos Ltd (STO) losing 1.8 percent.

Gold stocks .AXGD touched a two month low. Newcrest Mining Ltd (NCM) and Northern Star Resources (NST) were among the worst performers.

Miners' losses were offset by gains in financial stocks with Westpac Banking Corp (WBC) gaining 0.5 percent and Australia and New Zealand Banking Group (ANZ) up 0.65 percent.

New Zealand's benchmark S&P/NZX 50 index (nz50) was 0.28 percent, or 20.81 points, lower at 7378.02. The benchmark closed flat on Wednesday.
