An e-bike battery is believed to be the cause of a fire that broke out at Rafferty's Resort on Sunday morning.
Firefighting crews from Wallarah, Lake Munmorah and Swansea were called to the Cams Wharf resort just before 2am Sunday.
They arrived to find large volumes of smoke coming from a shed and quickly worked to control the blaze.
Firefighters started an external knock down before gaining access through the rear of the shed. Crews managed to extinguish the fire, preventing it from spreading to the roof cavity or the adjoining house.
Wallarah Rural Fire Brigade reported the fire initiated from an e-bike battery that was on charge.
The occupants of the home were all accounted for at a neighbours house after reporting the fire.
