The Australian Industry Group (AiG) released its construction data for Australia on late Sunday evening. The Ai Group/HIA Australian Performance of Construction Index fell to 50.7 in November from 52.1 in October.
A reading above 50 indicates expansion in the sector.
The decline was mainly driven by a drop in house building and commercial and engineering construction.
"The continuing boom in apartment building saw a slight lift in the overall construction sector in November despite falls in house building and commercial and engineering construction," Ai Group Head of Policy, Peter Burn, said.
