Adels Grove Resort has confirmed the overnight fire has destroyed their main building but miraculously none of 500 people on site at the time during the school holidays were hurt and they remain open for business.
The resort said the fire impacted the reception/shop, restaurant, deck and bar with no injuries reported.
"An 82-acre holiday park, we have 61 accommodation rooms and glamping tents plus 235 camp and caravan sites which are relatively unaffected," Adels Grove said on their Facebook page.
They also confirmed most tourists there will stay on despite the setback.
"While we regroup we believe the temporary loss of services should not impact the vast majority of our visitors provided they are self-sufficient and equipped with supplies," they said.
"With many campers opting to remain in the park to continue their holiday the Lawn Hill Gorge boat tours are running and canoe hire is open for business.
"Thank you to everyone for their patience with temporary arrangements for check in and alike."
Any travellers or guests wanting further information or assistance can call 0474 522 146 while phone lines are re-established.
Resort Manager Michelle Low Mow said they woke up at 12.45am to find the resort's main building alight.
"Lawn Hill Gorge is still perfect, so we have to see if our campground can keep operating," Ms Low Mow said earlier this morning.
