Already $6 million has been realised from the sale of two sites at Salamander - one to the Aldi supermarket chain another to local doctors for a new medical centre.

But the TRRA says those sales should not have proceeded until a master plan for the council land holding at Salamander was prepared.

Ms Foster said the council had worked hard to create a development application (DA) covering the future use of its 11ha land holding at Salamander.

The application covered all the bases in terms of environmental, infrastructure and community needs.

The TRRA has also questioned the council's decision to negotiate sales behind closed doors rather than go to the market and seek expressions of intertest.

Ms Foster, however, refuted any accusations the sales of land had been conducted in a non-transparent way.

"We have followed the legislative process," she said.

"The only confidential business papers relating to the land that are not available for public viewing are the reports relating to the sale prices for the lots."

Ms Foster said other concerns raised by the TRRA in regard to existing community services such as the library and childcare centre were unwarranted, as were questions regarding a lack of pedestrian links.

"There will be no changes to those facilities (library and child care) within the next 10 years," she said.

It was not viable to move them in the short to medium term.

"The development will also provide new footpaths, road network and cycleways that link all of the proposed businesses with the existing community facilities," she said.

As well, residents adjacent would not be affected by traffic moving in and out of the site.
