Dec 6 (Reuters) - Australian shares fell on Wednesday, as material stocks slipped on weak base metal prices while data showing the economy expanded at the fastest annual pace in over a year in the third quarter had little impact.

The S&P/ASX 200 index (xjo) dropped 0.4 percent, or 26.12 points to 5945.70. The benchmark shed 0.2 percent on Tuesday.

Data from the Australian Bureau of Statistics showed gross domestic product (GDP) in July-September grew 2.8 percent from a year earlier, but worrying weakness in household spending cast a cloud over the growth outlook.

The metals and mining index .AXMM fell 2.1 percent to its lowest in over a month, with Rio Tinto (RIO) slipping 1.7 percent and BHP (BHP) losing about 2 percent.

Iron ore futures in China slipped on Tuesday while copper had its biggest drop in two years as the dollar firmed against a basket of currencies on expectations of a U.S. tax reform. [IRONORE/] [MET/L]
