SA to replace 4500 public houses

About 4500 public housing properties across South Australia are to be replaced over the next 15 years.

The government will spend $22 million in the first round of projects to bulldoze 65 existing Housing Trust properties and replace them with up to 90 new homes.

The current homes pre-date 1968 and are spread across Adelaide's suburbs.

Housing and Urban Development Minister John Rau says the first nine projects will generate about 105 jobs.
