The Tasmania Fire Service is bringing in extra resources to fight a large bushfire burning near St Helens on the state's east coast.
The fire danger rating is expected to be high over the next two days, and very high on Saturday.
The blaze, which started a week ago, came within 50 metres of homes and property at Goshen.
So far it has destroyed more than 7,500 hectares.
Incident controller Steven Richardson said the fire was unpredictable and there were concerns dry conditions would encourage the blaze to spread quickly and impact on coastal communities.
The TFS is deploying an aggressive fire control strategy to ensure the blaze does not get out of hand.
"We've got a few people coming in from right across Tasmania," he said.
"We also have the State Emergency Service working with us to help us do assessments of outlying areas that are not impacted by fire at this stage it's just that we like to always plan well ahead," Mr Richardson said.
"This may involve the use of a Large Air Tanker C130 from New South Wales for aerial retardant runs, with a focus on protecting communities south of St Helens, including Upper Scamander and Trout Creek.
"Our priority is to protect people, communities and property."
With Thursday's public holiday for the Hobart Show, holidaymakers heading to the east coast are being encouraged to be aware of the fire situation.
"We just want people to be mindful of where this fire is," he said.
"So just keep up to date with the information, go about their normal weekend activities and just enjoy that time with family and friends.
"But please stay away from the area where the fire is and don't go venturing off into those forest tracks."
The TFS will provide regular updates and people are encouraged to listen to ABC radio.
Meanwhile, the Parks and Wildlife service has banned campfires and pot fires at some east coast camp grounds.
The ban spans reserves from the Mt William National Park to Orford, including Maria Island and Lime Bay.
Bushwalkers are being encouraged to lodge their trip intentions in log books at visitor centres and talk to local Parks staff for the latest information.
