Some Australians are not impressed by how their country's wealthiest citizens have responded to the country's disastrous wildfires.

An estimated 25 million acres of Australia's brush have burned since September, killing at least 28 people, forcing hundreds of thousands of others to evacuate, and blanketing cities in dangerous smoke.

Famous Aussie multimillionaires including Liam Hemsworth and Nicole Kidman have pledged hundreds of thousands of dollars to relief efforts, but some business figures have been slower to respond publicly, leading to outrage online. The criticism on this front has largely been led by Australian comedian Celeste Barber, who led the largest Facebook fundraiser in the platform's history to benefit relief efforts.

Barber also called out the difference in billionaires' responses to the Australian fires and the Notre Dame fire in April 2019. Within hours of that incident, three French billionaires - who, it bears noting, are all significantly wealthier than anyone in Australia - had already pledged $565 million for restoration efforts, Business Insider's Katie Warren reported at the time.

Barber tweeted: "Hey billionaires, Notre Dame burning down sucked. I get it. Times that by a trillion and that's what's happening in Australia. Feel free to flick us a quick couple of million. You make it seem pretty easy."

The criticism hasn't been limited to Australian billionaires, however. Jeff Bezos was slammed on Twitter after announcing that Amazon would be donating $690,000 - roughly the amount of money he makes in five minutes - to the recovery efforts, Business Insider reported.

Here are the donations Australian billionaires made to recovery efforts, listed in chronological order. Business Insider will be updating this list as new donations are made.
