It's not all bad news for Grantham after the loss of the town's only hotel, with Mayor Steve Jones announcing the town will be the first in south-east Queensland to get the National Broadband Network (NBN).

New residents and businesses will have connection to the fibre optic network, with speeds 10 times the speed of standard internet connections, by Christmas this year which will initially see 150 Grantham residents in the new estate receive the NBN one year before the rest of the south-east.

Cr Jones said since news of the connection was released by the media, there had been numerous inquiries from business people looking to purchase land in Grantham as the area was seen as a major business corridor between Brisbane and Toowoomba.

"The new estate will have the cables installed as part of construction," he said. "In renewing other services to the town, the trenching will be in place to facilitate the new cables, so the rest of the town will follow shortly after."

Grantham residents were hit hard in the January 10 floods, with more than 130 houses damaged.

About a third of the residents are being shifted to a new estate on a hill near the town.

It is also the first time in Australia a government has sponsored a land swap, with a land ballot conducted to determine which block residents could relocate to 'the hill'.
