A firefighter who was knocked unconscious by a falling branch while battling a massive bushfire in northern NSW rains in hospital in a serious but stable condition.
The man suffered head and chest injuries when struck by a falling branch on Tuesday. He was winched out of the Wolli National Park and flown by helicopter to John Hunter Hospital.
NSW Rural Fire Service Inspector Ben Shepherd says the firefighter is receiving further treatment in hospital surrounded by his family.
\"But he is in good spirits,\" Mr Shepherd told AAP on Wednesday.
The so-called 695 fire near Putty northwest of Sydney has already chewed through at least 18,500 hectares of bushland as water-bombing aircraft continue their runs over the blaze.
Further north, another major fire is burning on steep and heavily timbered country at Bobbiwaa Creek. It\'s expected to last for days if not weeks.
Smoke and flames may be visible as far away as Narrabri and Bingara with homeowners advised to \"monitor your property for spot fires\".
At least 35 fires are burning across the state but no fire bans are currently in place.
