Building approvals rose strongly in May 2012, up by 27.3 per cent nationally according to the ABS figures.

Multi-unit approvals rose by 58.3 per cent in May 2012 to be up by 41.5 per cent on May 2011, while detached housing approvals were up by 9.0 per cent in May 2012, but down by 8.5 per cent when compared to May 2011.

The May result follows a 7.6 per cent fall in total approvals in April to their lowest level since May 2009.

The Housing Industry Association (HIA) noted it was a rare piece of positive news for the new home building sector.

“This result provides some hope of an improved new home building outlook emerging in time and delivers preliminary evidence that recent interest rate cuts may be starting to have an impact," said HIA Senior Economist, Andrew Harvey.

"However, we need to keep in mind that the result comes off a very low base in April and is driven by the highly volatile multi-unit part of the market. The level of approvals in the core segment of detached housing remains well below the levels recorded one year ago," said Andrew Harvey.

"Key factors behind the strong May result include a partial rebound in Western Australia which saw approvals up by 24.8 per cent in May after a 47.2 per cent fall in April, along with a similar rebound in South Australia. There is also a "bring forward" effect in both Victoria and NSW where buyers have rushed into the housing market to secure state government home buyer incentives before they end on 30 June 2012," said Harvey.

In May 2012 total seasonally adjusted building approvals rose by 25.1 per cent in NSW, 31.8 per cent in Victoria, 10.3 per cent in Queensland, and 16.2 per cent in Western Australia. In trend terms, total approvals rose by 21.5 per cent in the Northern Territory and by 27.5 per cent in the Australian Capital Territory. Tasmania was the only jurisdiction to experience a fall in approvals in May 2012, down by 12.1 per cent in seasonally adjusted terms.
