KAIRABAH south of Yarrabilba has officially become Logan's 64th suburb, with the Department of Natural Resource and Mines (DNRM) signing off on it last week.
The name Kairabah is pronounced care-a-bar and means "place of the white cockatoo" in the Yugambeh language.
The boundary change affects only the unoccupied southern end of Yarrabilba and was made in anticipation of the development's growth.
Mayor Pam Parker said Kairabah would be a key future population centre for the south-east region.
"Logan is a city on the move and the establishment of Kairabah as our 64th suburb will support sustainable future growth as residents continue to move into the city due its ideal location," she said.
"The City of Logan is home to more than 300,000 residents and sustained population growth of 2.2 per cent per year will see that number approaching 500,000 residents by 2031."
She said the name Kairabah was recommended by the Yugambeh Museum, Language and Heritage Research Centre.
"Extensive consultation was carried out with the local community and council has worked closely with Lend Lease and the Department of Natural Resources and Mines throughout the process of creating a new suburb for the city," she said.
Division Four Councillor Don Petersen said the new suburb will be developed over the next decade and boundary change will support the delivery of infrastructure including future roads and water networks.
"The establishment of Kairabah is an important step in managing growth and meeting the future needs of the local community," he said.
New suburbs are also proposed in the Greater Flagstone area with Logan City Council encouraging residents to have their say when formal public consultation is announced by DNRM.
