Cr Parker remained tight-lipped on the issue when ABC 612 Breakfast host Spencer Howson asked her if the US company was scouting for potential sites in Logan.

"We have had confidential discussions with Costco, Spencer. That's all I'll say at this time," Cr Parker said on Monday morning.

A council spokeswoman said Costco had been in talks with the City of Logan for several years, but no formal development applications had been made.

"Council has been proactively promoting the City of Logan, over a long period of time, as a potential location to hopefully accommodate Costco's future expansion plans into the broader region," she said.

"The City of Logan is strategically located between Brisbane and the Gold Coast and would be the ideal place for Costco to establish such a prominent business. We would certainly welcome Costco to our city."

A Costco Australia spokeswoman also confirmed that that company had been scouting several potential sites.

"We certainly are in talks about potential sites but until we have applied for a development application, there is nothing further we can reveal," she said.

The spokeswoman said Costco planned to open one new store this year, however it was in Melbourne. She said the warehouses normally took about six months to build.

Costco opened its first Queensland store in North Lakes last year, with the membership-only wholesaler offering discounted rates on everything from sausages to televisions to car tyres.

The retailer has seven warehouses in Australia and has plans to build another Queensland location within the next two years.

Despite an increase in revenue, Costco Australia ran at loss last financial year after opening three new stores.

In January, Costco Wholesale Australia managing director Patrick Noone said he expected the business to post a profit this financial year and generate $1 billion of sales revenue.

"Overall, the number of customers shopping with us is growing and the volumes are ­growing as we add more stores," Mr Noone told Fairfax Media.
