Brisbane’s biggest developer has started to deliver its first “crescent” development projects with the state Government.

The Crescent Development Project Authority said the first three projects would be finished by the end of this year.

“The Crescent Project will help deliver economic growth for our region and provide a sustainable and secure future for our residents,” Ms Muthu Mahutwani, Queensland Minister for Local Government and Communities, said.

Key points: The first three “coupons” are expected to be finished this year by the state’s Development Agency (DA) project management teamIt is the first time a developer has managed a project to go ahead without a final decisionThe Queensland Government is working with Crescent Development Projects Authority to help the Queensland Government find its way through the state election processIt is expected to bring up to $1 billion in economic benefits to the Queensland economy.

A total of nine projects are currently being considered by the Queensland Development Agency.

They will be built on land currently owned by the Government of the Territory.

Queensland Development Agency chairwoman Helen Williams said the Authority wanted to ensure the project could proceed in a responsible way.

Ms Williams said all the projects were still subject to the requirements of the Queensland Planning Act.

“[They’re] the final stage in the planning process, and there are still some things that we need to get done in the development process before we can actually commence with the actual projects,” she said.

Ms Williams and Crescent Development Authority chairwoman Elizabeth Sarns have worked together to find a sustainable way forward for Queensland and the State.

In the early stages of the process, the Authority and developers had been in negotiations for years, with both sides saying they wanted to build projects in Queensland.

Ms Sarn, who has worked for the Authority for more than 20 years, said the state had not been able to find an agreement to develop the projects.

She said the Queensland government was not taking any risks and was committed to the projects being approved.

But Queensland Premier Annastacia Palaszczuk has called on the Queenslanders to stand together to stop the projects from being completed.

Premier Annastacian Palaszikszczak said the projects would deliver economic benefits, but there were “real risks”.

“We can’t have this sort of project, which is not going to produce any economic benefit for Queensland, because we are not ready to go through the process of getting it approved,” she told the ABC’s Lateline program.

“We have to make sure it’s done in a safe and responsible way, that we are really making sure it is done right, and that it’s going to deliver economic benefit.”

Ms Williams agreed the Authority was concerned about the risks, but the Authority would not say if the Authority had made a formal submission to the State Government or the Queensland Parliament.

“This is a very important project that’s been approved,” Ms Williams said.

“There is still a lot of work to do.”

Ms Sorkasz said she hoped the projects could create jobs and support residents.

“I think this is really good news for the community in the Crescent, the Crescent development area, and the people who live in that area,” she, Ms Williams and Ms Mahutws said.
