SYDNEY/WELLINGTON, Nov 2 (Reuters) - Australian shares fell for the sixth consecutive session on Monday, with losses across the board as investors awaited an interest rate decision by the Reserve Bank of Australia.
The S&P/ASX 200 index .AXJO tumbled 1.3 percent or 70.63 points to 5,168.50 by 2:55 GMT. The benchmark bounced 4.4 percent higher last month.
Sentiment remained bearish after recent data out of China was too mixed to ease worries about slowing growth in the Asian economy.

The financial sector was hit hard with Westpac Banking Corp WBC.AX off around 2.2 percent. The nation's third largest-lender by assets posted a 3 percent rise in annual profit, but highlighted a fragile outlook with modest credit growth, intense competition and ongoing regulatory uncertainty.
The downbeat sentiment was felt through the sector with Commonwealth Bank of Australia CBA.AX and ANZ Bank ANZ.AX off around 2 percent, while National Australia Bank NAB.AX dropped 1.6 percent. Macquarie Group MQG.AX was the clear underperformer with a loss of nearly 5 percent.
Health care stocks too came under pressure with Sigma Pharmaceuticals SIP.AX off 3.6 percent, having run into profit taking.
Miners too suffered from ongoing weakness in metal prices and concerns about China, the world's largest importer of commodities. BHP Billiton (L:BLT) BHP.AX was down 0.4 percent.
Oil and gas producer Santos STO.AX stood among the rare winners with a 3 percent rise after Malaysia's Sona Petroleum SONA.KL agreed to buy its Stag oil field for $50 million.
New Zealand's benchmark NZX 50 index barely moved on Monday as the market continued to consolidate after touching an all-time high of 6,014.48 points last week. It was trading at 5,989.68, up 3.3 points or 0.06 percent, from Friday's close.
The index had a 12-day rally which ended last week.
