UPDATE 3.10PM: A FIRE which gutted a shed at the Hervey Bay Historical Museum on Tuesday night has been declared not suspicious.
A Queensland Police Service spokesman said it was not clear what started the fire but said it was believed there was no suspicious circumstances surrounding the blaze.
Initial investigations had indicated the blaze may have been suspicious.
Emergency crews were called to the inferno just before 7pm on Tuesday and police have remained on scene for a majority of the day collecting evidence.
Hervey Bay Historical Village and Museum president John Anderson said it had been heart-warming to see so many people come out in support of the volunteer group.
"The generosity of people is quite overwhelming," he said.
Mr Anderson said the group had lost a number of tools as well as a 1934 Ford truck which had taken five years to rebuild.
The museum was open again today with a school group from Sharron State School, near Bundaberg, taking a tour.
UPDATE 6.30AM: A fire that broke out at the Historical Museum in Hervey Bay on Tuesday night is being treated as suspicious.
Queensland Fire and Emergency Services Inspector James Gill said fire investigators would be on scene on Wednesday to work to determine the cause of the fire.
The blaze, that started around 7pm, was contained and crews were able to stop the fire from spreading to major displays within the establishment.
Inspector Gill said five trucks and a back-up water tanker from the rural fire service was sent to the fire, along with a commander in control unit.
Inspector Gill was uncertain exactly what time the blaze was extinguished.
He said crews were also able to stop the fire from spreading to northern bushland.
Hervey Bay Historical Museum president John Anderson said it was lucky the fire engine (one of the displays) wasn't affected.
FOUR fire crews are doing their best to contain the blaze and prevent it from spreading to other sheds in the Hervey Bay Historical Museum and Village.
The fire crews are supported by a 4WD support vehicle and an operations truck.
Hervey Bay Historical Museum president John Anderson is at the Zephyr St museum in Scarness.
"The workshops are a huge asset," he told reporter Hayden Johnson.
"Luckily the fire engine is safe," referring to a display in one of the sheds.
Mr Anderson said he is unsure how the blaze began but they are determined to still hold Christmas carols this week.
Detectives are now on the site.
