Billionaire Bill Gates cuts a casual figure during the Australian Open in Melbourne

Bill Gates was back in attendance for another day of the Australian Open in Melbourne on Friday night.

The billionaire, who has also appeared in matches earlier this week, watched the semi-final singles match between Novak Djokovic of Serbia and Tommy Paul of the United States at Melbourne Park.

The 67-year-old mingled with the locals as he sat in the stands, wearing a simple black T-shirt.

The tech mogul added a cap with a white logo on the front and paired the ensemble with dark shorts.

Bill wore a pair of glasses and had a pass hanging around his neck on a lanyard.

The Microsoft founder looked quite animated at times and was clearly deeply involved in the match.

Gates is visiting the country with the Gates Foundation and representatives from his company Breakthrough Energy, which drives innovation in sustainable energy and technology to reduce greenhouse gas emissions.

He thanked and praised the prime minister for his ‘great partnership’ on international health issues, including the Global Fund to Fight AIDS, tuberculosis and malaria.

Gates also made headlines on his trip after warning that Australia had to be ready for the next pandemic, which he said could be man-made and far more brutal than Covid-19.

Speaking to the Lowry Institute in Sydney earlier this week, Gates said political leaders needed to put their differences aside and work together to prepare for the next virus.

“With the pandemic, we were fools not to have the tools, the practice and the global capacity to stand by like we do with fires or earthquakes,” he said.

The billionaire philanthropist called for greater global cooperation, saying the Covid-19 pandemic is an example of how countries can improve their response by working together.

But the tech pioneer has also been criticized for using his $70 million private jet while continuing to preach about the dangers of climate change.

The $70 million Gulfstream, which was spotted on the runway at Sydney’s Kingsford Smith Airport, burns around 1,700 liters of fuel per hour.

Gates owns a private jet, which has drawn criticism from some of his critics.

However, it has been known to offset its carbon emissions by using sustainable jet fuel and providing funds to a direct air capture company to remove carbon dioxide from the air.
