An independent report, commissioned by the Queensland government ahead of its decision on the controversial Cedar Woods development, has slammed Brisbane City Council's reliance on an agreement granted to an LNP donor to originally approve the $900 million mega-suburb.

Deputy Premier Jackie Trad is due to make a decision on the Upper Kedron development on Friday, after calling in the council decision to approve between 780 and 980 dwellings on the 227 hectare site, as part of a commitment Kate Jones made during the January election campaign.

The decision had caused outcry in the community, with objections based on limited road infrastructure to support the development and the impact on environmentally sensitive bushland.

In his report to Ms Trad's office, planning expert Greg Ovenden recommended the first stage of the project, thought to include about 145 lots, be approved.
