As the work continues to control the Moonbi fire, so do efforts continue to keep the crews fed and watered.

And at least one volunteer has said she's in it "for as long as they need us to do this".

Many people have donated cash, goods or food since the battle started on the Moonbi blaze, which appears to have been deliberately lit and has claimed more than 5000 hectares.

Among those people concerned for frontline volunteers' welfare are Kirsty Sutcliffe and Tianna Milovanovic, who have been gathering and delivering supplies to the Moonbi headquarters.

Ms Sutcliffe, a digital search and marketing specialist, said she had asked her local-business clients to pitch in for groceries, and it had "gone gangbusters".

On Wednesday and Thursday, she collected and shopped with $400 then $720 in cash and took it - along with boxes and boxes of donated food - to Moonbi.

"When the town needs to come together, they do it well," she said.

"You realise how much community spirit is out there when something like this happens. And everybody cares - some people just find it hard to put their foot in the door with what they can help with."

Ms Sutcliffe said she couldn't have done it alone.

"My clients are awesome ... We all pitched in."

Miss Milovanovic said she had been moved to action after calling catering HQ on Wednesday morning to ask what was needed.

"They told me, 'We ran out of this and we ran out of that, and some of the firies missed out on food last night ... I thought, 'That's not gonna happen again'," she said.

"My main priority is making sure our heroes in yellow, as I call them, are fed and watered.

"I just think, I'm here having my nice, cool drink of water and a hot meal at night, and they're out there literally saving our arses ... I want to make sure these guys are supported so they can continue to do their job."

Miss Milovanovic offered her garage on social media as a drop-off point for donated supplies - and has spent the past three days carting it to catering HQ.

"I'll do this for as long as they need us to do this - just like those guys up there are going to fight that fire as long as they have to ... until the danger's gone," she said.

She said the response to her call-out had had given her "the warm fuzzies".

"Everyone is contributing something, whether it's a business, a person working a full-time job or a pensioner who has no money but is going to bake some muffins and drop those down ... That's the Tamworth I love."

"No matter how big or small the gesture, it really makes me proud to be part of this community," Miss Milovanovic said.
