The Gympie Mayor says improved mobile phone reception is needed in western parts of the region, in south-east Queensland, to better protect against future flooding.

Ron Dyne says the local disaster group could not get information about creek and river heights in Widgee, Wide Bay and Glastonbury Creeks at the height of last week's flood.

Councillor Dyne says waterways rose quickly in these areas but locals could not relay updates when the internet and landlines failed as there is no mobile reception.

"Somewhere along the line someone needs to put some thought into putting in better mobile reception," he said.

"I go to Vietnam and you can get reception in the Mekong Delta which [is] seven kilometres wide and get mobile reception but a kilometre out of Kilkivan and I get no mobile phone reception."
