Barber fought back tears on Saturday morning as she woke to the amount donated and thanked her followers for the donations.
"This is out of control! You are all out of control. My love and appreciation for you all is out of control," she wrote. "Unfortunately today the fires are due to get even more out of control. Thank you."
NSW Premier Gladys Berejiklian declared a state of emergency across the state as tens of thousands of people were fleeing devastated areas on the NSW South Coast ahead of the worsening conditions on Saturday.
Over the weekend, Channel 7 spoke with Barber as she loaded supplies for firefighters into her car.
When asked if she was surprised by the response of the fundraised, she said: “People are amazing. Power to the people. Someone needed to do something and the people have done something."
