Serena Williams shows off tribute to koalas through her nail art during Australian Open

While many are celebrating Serena Williams' amazing win during the first day of the Australian Open, other fans were quick to spot her meaningful manicure as well.

During Wednesday's match against Slovenian tennis player Tamara Zidanšek, the U.S. star wore a purple leopard print look that she paired with a multi-colored french manicure that included an accent nail featuring a design of a koala.

The artists behind Williams' nails thanked her for the opportunity to service her in an Instagram post.

"The adorable manicure is an apparent nod to Australia as the country battles a devastating bushfire crisis that has so far wiped out more than 25,000 koalas," the artists wrote.

This isn't the first time Williams has paid it forward to Australian wildfire relief efforts. Earlier this month, she also donated prize money from winning her first title since having her daughter Alexis Olympia Ohanian Jr.

Additionally, she posted a thoughtful message that included koalas being rescued on Jan. 9, which has since been liked more than 200,000 times.

"I am heartbroken over the devastation of the wildfires in Australia," Williams said. "With the loss of over 500 million animals and many people left without their homes, we need to act now to help in whatever way we can. I have been going to Australia for over 20 years so this devastation is hitting me particularly hard."

Williams concluded her post by highlighting ways to donate and support organizations that are working toward rehabilitating Australia's wildlife.
