Near Sydney, a bus carrying wedding guests rolls over, killing 10 people and injuring another 25.

In Australia's wine country, a bus transporting wedding guests overturned on a cloudy night, killing 10, and wounding 25, according to authorities.

According to Police Assistant Commissioner Tracy Chapman, the 58-year-old driver was detained and will face charges while being held at a Cessnock police station. She refused to go into detail about the accusations, including if speed played a role, but she did tell reporters that "there is enough material" to support filing charges.

At a roundabout on Wine Country Drive in the town of Greta, in the Hunter Valley district of New South Wales state, north of Sydney, the accident happened shortly after 11.30 p.m. in foggy weather.

The guests were travelling to their lodging in the town of Singleton after attending a wedding earlier that day at the Wandin Estate Winery, according to Chapman. One visitor told Seven News that the wedding was like something out of a fairytale.

The 25 injured people were transported by car and helicopter to hospitals. 18 further passengers were unharmed.

Since the "emotional scars of tragedy will not go away," Prime Minister Anthony Albanese hailed first responders and extended government support to victims and their families.

"It is so cruel, so tragic, and so unfair for a joyful day like that, in a beautiful area, to end with such horrible loss of life and damage," Albanese told reporters. "Many hire buses for weddings to ensure the security of their guests. And that only serves to highlight this tragedy's unbelievable scope, said Albanese.

The crash, according to Cessnock's mayor Jay Suvaal, was "really horrible."

The Hunter Valley is a popular wedding and tourism destination, so there will likely be visitors from all over the state and the country who have been there and done similar things, he said. "I believe it will stun the entire community," the speaker said.

Greta is located in the gorgeous Hunter Valley wine region, which is home to several vineyards and dining establishments. It was Australia's first wine region to be formed.

The wedding took place in the middle of a long weekend, and most Australian states had public holidays on Monday.
