A $1.2 billion deal to secure the infrastructure needs of Flagstone and Yarrabilba over the next 45 years has been signed.
The Queensland government, Logan City Council and nine developers including Peet and Lendlease have reached agreement on the plan to provide local roads, water and sewage facilities to the growing communities up to 2066.
Planning Minister Cameron Dick said two primary schools, retail precincts, community hubs and major sports and recreational parks had already been built across Yarrabilba and Flagstone.
"Flagstone and Yarrabilba are in Queensland's fastest growing population corridor, with estimates that by 2066 there will be 200,000 people living in these areas," Mr Dick said.
"Some 170 kilometres of council roads will be upgraded through developer contributions and over the next six years alone, the agreement will see up to $400 million in infrastructure investment, which will support more than 130 construction jobs each year."
Over the next six years there will be funding upgrades for Chambers Flat Road, Teviot Road, New Beith Road, Johnson Road, Logan Reserve Road, Stockleigh Road, Edelsten Road, Crowson Lane and Cusack Lane.
There was no funding announced for Mount Lindesay Highway upgrades or Salisbury to Beaudesert passenger rail.
Scenic Rim MP Jon Krause said it would be a missed opportunity for there to be no Mount Lindesay Highway funding flowing from infrastructure agreements with developers.
"These two areas (Flagstone and Yarrabilba) are feeding a big increase in traffic on the Mount Lindesay Highway," he said.
"I have called on the government to get on with plans, especially for fixing the Jimboomba bottleneck in the budget."
A Department on Infrastructure and Planning spokesperson said the $1.2 billion agreement was designed to fund local government services including water supply, wastewater and local roads.
"The Mount Lindesay Highway is a state road and the Department of Transport and Main Roads has several upgrade projects proposed for the Mount Lindesay highway over the next 9 years, including $74 million funds already committed for design and construction," he said.
"In the longer term, Greater Flagstone PDA will be serviced by a new passenger rail line between Salisbury to Flagstone as identified in ShapingSEQ, SEQ Regional Plan 2017. Long term regional planning by the Queensland Government has identified a need for additional public transport infrastructure to service this future growth area."
Logan MP Linus Power and Jordan MP Charis Mullen supported the agreement.
Logan City Council's interim administrator Tamera O'Shea said the historic agreement would see developers fund infrastructure needs through upfront charges.
"This guarantees the roads, water supply and wastewater infrastructure needed to connect the emerging communities with the surrounding networks are delivered without placing an impost on existing ratepayers."
