The Queensland Housing Industry Association (HIA) says the downturn in the sector cannot get any worse, with figures showing building approvals dropped 19 per cent in Brisbane over the last 12 months.
However, building activity increased 53 per cent in Toowoomba on the state's Darling Downs in the same period.
HIA state executive director Warwick Temby says new figures show the construction sector is reflecting Queensland's two-speed economy.
"It shows the housing industry's probably at the bottom of the trough across Queensland, but the picture's very patchy," he said.
"Anywhere that's anywhere near a resources area seems to be doing pretty well.
"Places that aren't near resources areas are struggling." Mr Temby says builders are more optimistic about the future.
"We're certainly optimistic that a combination of lower interest rates and 15,000 first home buyer grant that the Government introduced in the budget will help turn things around in 2013," he said.
