Jim Simpson was born and bred in Gregadoo and his family has owned land there since 1902.

Mr Simpson, along with three other people, including Malcolm Edgar, proposed a subdivision of a combined 1200 acres in 2013 that had the potential for about 3600 residential lots.

Land at Gregadoo made it to the Wagga Spatial Plan, which sets out guidelines for the city's development through to 2043.

According to the plan, the Gregadoo land - referred to as area 20 - falls outside the containment line and while it has the ability to support residential demand in the longer term, it will only be considered for rezoning if it meets two requirements.

Firstly, after a residential study of the local government area has been undertaken and secondly, that land within the urban containment line is exhausted to less than 15 years supply.

"This is rural-residential and it's only about three kilometres from the airport ... and with the runway expansion, this would be another fantastic thing for Wagga," Mr Simpson said.

"The road network too is halfway there ... and also to get to the Bomen Industrial Hub, it's just across the Eunony Bridge and there's basically a straight line up through Byrnes Road."

Mr Edgar said people are constantly crying out for more land as the city's population is expected to grow towards 100,000.

"So many people say we need more land, builders are asking what's happening with your subdivision?" he said.

"With 1200 acres, say at three blocks per acre, we're looking at 3600 blocks of land and that's a very substantial suburb.

"We've got the land, it's prime land and it's ready to go."

However, city strategy manager Tristan Kell said there is still a "fair bit" of land available within council's containment line and it is important to use existing infrastructure first.

"We know that single dwellings, with backyards, are certainly the most popular type of housing within the regions and Wagga and we need to continue to provide that," he said.

"The key with land release is infrastructure.

"The challenges with the land we've released in the last 10 years, with the northern growth area, is servicing and that's hard infrastructure like sewer, storm water, parks, schools and access to neighbourhood shops."

Mr Kell said these elements need to be considered first before releasing more land to ensure that it can be serviced from the start.

"In the northern growth area there's potential for 25,000 homes and it's not finished yet," he said.
