Sept 30 (Reuters) - Australian shares fell more than 2% on Wednesday, with miners and financials suffering major blows, as investors tracked Wall Street futures lower after the first U.S. presidential debate stoked caution and uncertainty ahead of the election.
The S&P/ASX 200 index ended 2.3% lower at 5,815.9, posting their third straight session in the red. The benchmark snapped a five-month winning streak, and lost 1.4% during the quarter.
U.S. President Donald Trump and Democratic rival Joe Biden debated on Wednesday as markets pulled back from early gains, with the U.S. stock futures retreating after Trump cast doubt on whether he would accept the election’s outcome.
S&P 500 futures were down 0.6%, with Dow Jones and Nasdaq 100 futures each losing as much as 1% after the debate.
“The U.S. elections, and today’s debate, is adding an extra level to an already uncertain market,” said Brad Smoling, managing director at Smoling Stockbrocking.
“No matter what the outcome of the elections, it will be contentious, and it will add more uncertainty to the equities,” Smoling added.

Global iron ore mining giants BHP Group and Rio Tinto ended 2.9% and 1.3% lower, respectively.
