The S&P/ASX200 fell 11.9 points, or 0.13 per cent, to 8,853, as the broader All Ordinaries lost 7.8 points, or 0.09 per cent, to 9,120.9.
"We saw that early weakness as the ASX 200 fell about 70 points in early trading and for the fourth session in five, it ran into buyers lurking below that 8800 level," IG market analyst Tony Sycamore told AAP.
"It had that fabulous run higher in August, and now we're just sort of seeing a bit of consolidation, a bit of sideways price action."
The subdued session also came ahead of local labour force data and a US interest rate decision later in the week, Mr Sycamore said.
Only four sectors finished down for the day, but materials stocks (-0.5 per cent) were heavy with weakness in large cap miners and some profit-taking in gold plays following last week's rallies.
Evolution Mining handed back more than half of the previous week's 9.6 per cent gains, as spot gold hovered near its $US3,763.96 ($A5,522) an ounce record.

Financials stocks slipped 0.2 per cent amid mixed performances for the big four banks, as ANZ and CBA slipped 0.6 per cent each and NAB and Westpac rose similar amounts.
ANZ avoided downgrades from ratings agency Fitch and investment giant Citi despite copping a record $240 million fine for widespread misconduct in bond trading and customer dealings.
Meanwhile, AMP shares surged 6.5 per cent to $1.80 after the financial services group announced an in principle $120 million class action settlement over excessive fees charged by three of its superannuation subsidiaries.
Consumer-facing stocks did well, with discretionaries up 0.6 per cent and staples lifting 0.3 per cent, each tracking with gains in their respective segment heavyweights, Woolworths, Coles and Bunnings owner Wesfarmers.
Mexican-inspired fast food chain Guzman y Gomez jumped more than five per cent despite going ex-dividend, while Credit Corp lost 1.5 per cent as it locked in its dividend recipients.

The Aussie dollar is clinging onto recent gains, fetching 66.57 US cents and on par with Friday evening, supported by strong iron ore prices last week and as US rate cut hopes weigh on the greenback.
