Billionaire Bill Gates was spotted at the Australian Open in Melbourne on Thursday night.

Wearing a beige shirt and matching shorts, he pointed to the players and chatted with his sister.

The Microsoft founder is currently down under after attending a meeting with Anthony Albanese, the Prime Minister of Australia.

The two met at the Prime Minister’s residence at Kirribilli House to discuss climate change, energy and health issues.

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

He thanked and commended 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 Australia must be prepared for the next pandemic, which he says 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 need to settle their differences and work together to prepare for the next virus.

“In the pandemic, we were foolish not to have the tools, the practice and the global capacity to be prepared like we do with fire or earthquakes,” he said.

Calling for greater global cooperation, the billionaire philanthropist said the Covid-19 pandemic is an example of how countries could improve their response if they worked 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 spotted on the tarmac at Sydney’s Kingsford Smith Airport burns about 1,700 liters of fuel per hour.

Gates is believed to own four private jets, which has drawn criticism from both his supporters and critics.

The private jet collection is said to be worth $194 million and includes two Gulfstream G650ERs, valued at $70 million each, which can carry up to 18 passengers.
