The bushfire fundraiser started by Australian comedian Celeste Barber just keeps on climbing, with more than $22 million raised and more donations flooding in.

The online fundraiser is seeing about $10,000 in donations every minute.

Barber is known worldwide for her celebrity parodies on Instagram, and called on her significant social media following yesterday to raise money for Australian firefighters amid the bushfire crisis.

"This is my mother in laws house. It's terrifying," Celeste Barber posted on Facebook. (Facebook)

The funny woman sparked the mass movement when she posted photos of her mother-in-law's home in Eden, which is one of many NSW South Coast towns at risk from the fires sweeping Australia.

"This is my mother in laws house. It's terrifying," Barber said in the post.

"They are scared. They need your help. International donations can be made via the link in my bio."

The bushfire tragedy has attracted the attention of international mega-star Pink, actress Selma Blair, and US comedians Ellen Degeneres and Gary Janetti all pledging money to the NSW Rural Fire Service.

Barber responded to the overwhelming this afternoon, tweeting: "This is incredible. Power to the people."

Known for her comedic parodies of celebrity social media posts, Barber 's plea for help for the NSWRFS has exceeded expectations. (Celeste Barber Facebook)
