In the space of three weeks Bill Morris has lost his soulmate to cancer and his house to a bushfire.
Family friend Kylie Kinnish says Mr Morris was evacuated from his Upper Colo property two days ago as the 100,000 hectare Gospers Mountain fire started to close in.
On Friday night he was given the "devastating" news that his home of 30 years had burnt down, Ms Kinnish said.
Just three weeks before that his wife Elaine died of cancer.
"Him and Elaine lived on a property up there for over 30 years," Ms Kinnish told AAP on Saturday.
"Elaine passed from cancer in late October. Him and his son, they got evacuated from the property two days ago.
"Then they got the news that the house has burned down. It's really devastating, they've lost a lot."
The uncontrolled Gospers Mountain bushfire, which is burning through more than 100,000 hectares in the Hawkesbury region, is unlikely to be contained before weather conditions worsen later in the week, the NSW Rural Fire Service says.
Firefighters back burned through Friday night to get a handle on the massive blaze.
The fire has destroyed at least six homes since catastrophic conditions were declared on Tuesday.
Ms Kinnish said Mr Morris and his six children were "doing it pretty tough".
"They've lost a lot. The six kids have lost their mum and now they've lost all of her stuff.
"They got their animals out, which was great. Other than that the house is completely gutted."
Ms Kinnish, who lives near Windsor on the northwestern outskirts of Sydney, has started a fundraiser to help the Morris family and said she had been overwhelmed with support so far.
"My phone is going ballistic. Every time someone donates I get an email," she said.
In just four hours on Saturday afternoon the fundraiser has received almost $10,000 in donations.
Ms Kinnish is also organising furniture for Mr Morris.
Fire conditions in the Hawkesbury region - where the Gospers Mountain fire is burning - are expected to get worse early next week.
"On Sunday we are expecting similar conditions. Later on Tuesday the conditions will get worse as the heat starts building up," the Bureau of Meteorology said on Saturday.
"Tuesday and Wednesday will be fire weather days, with the weather conditions again deteriorating."
The Rural Fire Service said it was unlikely the Gospers Mountain fire would be under control before these conditions arrived.
