James said a number of analysts have expressed concern about the excessive strength of the housing market over the past month, but the August data shows some prospective buyers may be shying away from the market because of higher prices.
He still thinks the Reserve Bank of Australia will keep its cash rate unchanged at a record low of 2.5 per cent, as long as the US government comes to an agreement on the country's debt ceiling.
RBC fixed income and currency strategist Michael Turner said a correction in August after a string of rises in home loan approvals was to be expected.
"It is unlikely to mark the beginning of a weakening trend," Turner said. "We continue to expect modest growth in residential construction over coming quarters."
The Reserve Bank of Australia's August cash rate cut, to 2.5 per cent, should boost the housing finance figures later in the year.
"We expect the market for homes to remain broadly firm into year-end as the market adjusts to the August rate cut," Turner said.
"The flow-through to construction activity remains muted, however, despite the signals provided by higher prices."
