One woman even claimed she raised nearly twice what Amazon pledged by selling her nude photos online.
"Our hearts go out to all Austral as they cope with these devastating bushfires. Amazon is donating 1 million AU dollars in needed provisions and services. Find more about it and learn how customers can help as well," Bezos posted on Instagram.
This was enough to put the social media platforms on fire.
"Worldwide people have raised around $10 Billion....This dude could match that and still have $100 BILLION... Truly an inspiration," posted a user on Bezos' Instagram.
"So you're donating 690k US dollars to an entire country burning. Amazon makes about that much in 10 minutes," posted another.
To put things in perspective, Amazon today has a market cap of $936 billion.
Facebook has pledged $1.25 million towards bushfire relief efforts and metal band Metallica, which Forbes estimates is worth $68.5 million, has pledged $750,000 which is more than what Amazon has offered.
US media personality Kylie Jenner is even giving $1 million while Elton John has donated $1 million towards the Australian wildfires.
"This may sound horrible, but $690,000 is a pittance for #JeffBezos. That's like me putting $2 into the Salvation Army bucket," tweeted one user.
"Agree anything helps. However, when your [sic] the world's richest person and you only donate .000059 per cent of your worth, it's [what] makes you cheap. It's more of PR move on his part. Celebrities with far less money donated more," wrote one user under the Bezos post.
Instagram model Kaylen Ward told Buzzfeed that she's raised more $1 million by offering to send a nude photo to anyone who showed her proof that they donated to one of a list of organisations working in Australia.
Since September, fires have ravaged more than 80,000 square km an area larger than Ireland and left 28 people dead, besides an estimated one billion wild animals in Australia.
The fires have released some 349 million tonnes of carbon dioxide into the atmosphere over the past four months, according to the non-profit Journalists for the Planet, compared to 532 million tonnes of the country's total annual emissions in all of 2018.
