After revelations by the Canberra Times on Tuesday, the ACT opposition put pressure on Planning Minister Simon Corbell in the Legislative Assembly over the accusations relating to a proposed new Woolworths supermarket in Giralang.

Residents of the suburb weighed into the debate on Tuesday too, saying they wanted an end to the nine-year saga over their local shops and for the complex, which has stood derelict for years, to finally be rebuilt.

Mr Corbell confirmed in the Assembly during question time that his department was investigating allegations that a bid to build the Woolworths supermarket was underpinned by documents that played down the full impact of the development on the grocery business in Belconnen.

Both Woolworths and the owner of the site, Nikias Nominees, deny any misleading conduct.

In response to questions from Canberra Liberals' planning spokesman Alistair Coe, Mr Corbell said government lawyers were looking at the allegations made by Kaleen IGA owner Chris Haridemos.

"I have received a complaint from an individual relating to allegations of misleading information submitted as part of the development application process, leading to the approval of the development at Giralang shops," the minister told the chamber.

"I have asked my directorate and the Government Solicitor's office to consider these issues closely and to provide me with appropriate advice.

"That assessment is ongoing.''

The Giralang Residents Action Group said on Tuesday that the suburb had had enough of the wrangling over the site and just wanted its local shopping complex to be operational.

The group's spokesman, Bill Burmester, said the rival supermarket operators were "out-of-suburb" retailers whose actions had deprived Giralang of retail amenities for nine years to further their own business interests.

"I have requested a meeting with Mr Corbell to press the suburb's interests over those out-of-suburb retailers who have had a free rein for nine years, and probably hope to continue their good fortune at our inconvenience," Mr Burmester said.

This newspaper reported on Tuesday that an economic assessment impact, independently prepared by consultants Duane Location IQ, for the new shop at Giralang that was supplied to planning authority ACTPLA and the public estimated the Woolworths store would have sales of about $12.5 million in its first year, and its impact on existing retailers would be ''minimal''.

But in his official complaint to the minister, Mr Haridemos says internal Woolworths documents, obtained as part of a Supreme Court action against the development, put the estimated first-year turnover at more than $29 million.

The rival operators have launched several legal actions and the Australian Competition and Consumer Commission is still investigating allegations that Woolworths is trying to put other northern suburbs supermarkets out of business.
