FIREFIGHTING crews are expected to scale back their work to extinguish underground fires on part of Kooragang Island on Friday.
Fire and Rescue NSW Newcastle Commander Jeremy Stubbs said the fire was all but out and he expected the multi-government agency operation to wind back before the weekend.
The subterranean fires, which began burning in January, had caused some concern in the community.
The NSW Environment Protection Authority and Fire and Rescue NSW commenced an operation to extinguish the fires last Tuesday with help from the Public Works Advisory.
"We've been using water from the Hunter River and also fresh water through tankers to apply to six of the waste emplacement pits," he said.
"One of them in particular had a significant amount of fire in it.
"Each one of the other five that were left had hots spots in a number of different areas."
Mr Stubbs said he expected "extinguishment across the site" to be achieved within the next week.
