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 $US565 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 $US690,000 – 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.

Casino mogul James Packer was among the first Australian billionaires to donate, making two gifts totaling $US3.45 million through his company and family foundation.

Total donation: $US3.45 million ($US5 million AU)

Net worth: $US3 billion

Packer was one of the first billionaires to donate to the relief efforts, giving the New South Wales Rural Fire Service $US690,000 ($US1 million AU) in November, The Australian reported. Packer added an additional $US2.76 million ($US4 million AU) to his gift on January 6, only part of which will come from his personal foundation.

“Australians are digging deep to support each other in these tough times, it’s truly inspiring,” Packer said, according to The Australian. “My family and Crown are eager to do more and the best way we can help, is to significantly increase our donation.”

Packer built his $US3 billion fortune running the casino chain he inherited from his father, Crown Resorts, according to Forbes.

The cofounders of software company Atlassian, Michael Cannon-Brookes and Scott Farquhar, each donated $US770,000.

Net worth: $US9 billion each

Cannon-Brookes and Farquhar’s first $US70,000 donations were made through a charity auction for the hat Russell Crowe wore while cleaning his fire damaged property in November, Forbes reported. They subsequently promised to match the $US700,000 donated by their company’s charitable foundation,Forbes reported.

The pair built their multibillion-dollar fortunes as the cofounders and co-CEOs of collaboration software-maker Atlassian, according to Forbes.

On December 27, real estate billionaires John and Pauline Gandel donated $US690,380 to a group of organisations involved in the relief efforts.

The gift will be split between the Australian Red Cross, the Salvation Army, and St Vincent de Paul Society, The Sydney Morning Herald reported.

Pauline Gandel made in headlines last January when she criticised other ultra-wealthy Australians for not giving away more of their wealth while receiving an award on Australia Day in 2019,The Financial Review reported. “I hope to inspire others to be generous and improve our society,” Pauline Gandel told The Financial Review.

John Gandel built the couple’s $US3.8 billion fortune running women’s clothing retailer Sussan, but later pivoted to commercial real estate, according to Forbes. The billionaire is now part-owner of Melbourne megamall Chadstone.

On January 8, Gina Rinehart said she “privately” donated after being called out on Twitter.

Total donation: unspecified

Net worth: $US15.6 billion

Barber called out Rinehart by name for not making a public donation. “Hey Gina Rinehart where the hell are you and all your money?! If you’re in Hawaii on a family holiday I’m going to flip a f——- table,” Barber tweeted.

Rinehart responded to the attack through a spokesperson, saying that she had made a private donation. “(Mrs. Rinehart) is most concerned that the true causes of this sad devastation are tackled, rather than missed in the rush to blame climate change,” the spokesman said in a statement to The Daily Mail January 8 that also mentioned regulations on building dams and land clearing.

Rinehart, the executive chairman of iron miner Hancock Prospecting, has a $US15.6 billion fortune and is the richest person in Australia, according to Forbes.

On January 9, Andrew Forrest made what is believed to be the largest private donation by an Australian to relief efforts.

Total donation: $US48 million ($US70 million AU)

Net worth: $US8.9 billion

The Western Australian-based billionaire pledged to donate $US70 million through his philanthropic organisation, Minderoo Foundation, Business Insider Australia reported.

The first round of funds, $US10 million, will be spent immediately on disaster relief efforts, Business Insider Australia reported. The rest will be used to organise volunteers and fund future fire prevention efforts.

“We recognise that we don’t have all the answers, but we want to understand what communities need and do our bit to help them now and as they regroup in the coming months,” Forrest said, according to Business Insider Australia.

Forrest built his fortune off Minara Resources, the mining company he founded in 1994, according to Forbes.

Members of the Murdoch family pledged $US9 million amid public outrage over how their news outlets covered the fires.

Net worth: $US20 billion combined

Media tycoon Rupert Murdoch, his wife Jerry Murdoch, son Lachlan Murdoch and daughter-in-law Sarah Murdoch teamed up to pledge $US4 million of their personal funds to relief, The Sydney Morning Herald reported.

Their company, News Corp, pledged an additional $US5 million AU, according to The Herald. Days earlier, a News Corp employee spurred public outrage by accusing the organisation of leading a “misinformation campaign” with “irresponsible” and “dangerous” coverage of the wildfire disaster in a leaked email.

“I find it unconscionable to continue working for this company, knowing I am contributing to the spread of climate change denial and lies,” the email read, according to The Herald. “The reporting I have witnessed in The Australian, The Daily Telegraph and Herald Sun is not only irresponsible, but dangerous and damaging to our communities and beautiful planet that needs us more than ever to acknowledge the destruction we have caused and start doing something about it.”

In response, News Corp executive chairman Michael Miller told The Herald that the company stands by its coverage of the bushfires: “The dedication and professionalism of our journalists and photographers have kept the community – particularly those Australians affected directly – informed and supported. We respect Ms. Townsend’s right to hold her views but we do not agree with them.”

Kerry Stokes and his son Ryan announced they would be donating to the relief efforts in a memo to employees, the Sydney Morning Herald reported on January 16.

Stokes built a multibillion-dollar fortune running the Seven Group Holdings investment group, which owns media outlets and mining companies, according to Forbes.

Stokes and his son Ryan announced the pledge in a memo to his employees, according to The Sydney Morning Herald. “We believe the combination of our financial resources, our industry-leading equipment and our team’s motivation and skills is the most effective contribution we can make,” the memo read, according to The Herald. Stokes also gave employees volunteering with local fire services paid leave and offered local officials use of the company’s equipment.
