During this period, all campfires and solid fuel barbecues, such as wood, heat beads, charcoal, briquettes and hexamine, and stoves are banned.

Gas and electric barbecues and cookers are allowed if they are under the direct control of an adult, the ground within two metres of the barbecue is cleared of all flammable materials and there is an adequate supply of water (minimum of a bucket).

If there's a total fire ban in place, contact the local park office before using a gas or electric barbecue or cooker.

With a very high danger rating across the Mid Coast district, fire permits remain suspended.

Crews remain on site at the Thunderbolts Way near Giro and Kerriki Forest at Cooplacurripa as they continue to control large blazes. Both fires have burnt more than 1800 hectares.

Smoke drift was the cause of hazy sky across the Manning and Great Lakes at the end of last week.

According to NSW RFS district officer Stuart Robb, a combination of westerly and nor-east winds in the Coffs region that pushed smoke into a band just inside the coast was the cause of the drift.
