Nicole Kidman looks enviable at 57 on the beaches of Australia

At 57 years of age, Nicole Kidman is simply stunning and in her prime.

The Oscar winner showed off her toned physique while vacationing in the sun on a Sydney, Australia, beach during a getaway with husband Keith Urban last weekend, Page Six reported.

Kidman sported a tight black swimsuit that showed off her muscular legs as she emerged from the ocean.

Kidman and Urban, both 57, were joined by their 13-year-old daughter Faith Margaret, along with Kidman's sister Antonia, her husband Craig Marran and Antonia's 26-year-old daughter Lucia Hawley.

The photographs showed the group eating while sitting under a beach umbrella.

Kidman and Urban are also parents to 16-year-old Sunday Rose, who did not appear to accompany them. The actress shares two other children, Bella, 31, and Connor, 29, with her ex-husband Tom Cruise, to whom she was married from 1990 to 2001.

Nicole's return to Australia after her mother's death

This was the first time Nicole Kidman has been seen in her native Australia since the unexpected death of her mother, Janelle.

On September 7, the "Gone Girl" actress abruptly cut short her appearance at the Venice Film Festival after learning that her mother had passed away at the age of 84.

"I arrived in Venice and just after I landed my beautiful mum died," the movie star wrote in a letter that was read by "Babygirl" director Halina Reijn. "So I'm in shock. But I just want to say to [Janelle], she was the most wonderful, wonderful woman. She was a nurse and she trained and she had a great life, a big life. She influenced me and she influenced my sisters."

A month later, Kidman did not hide her feelings when talking about her mother's death on the red carpet at the premiere of the second season of "Lioness."

"It's been tough," he told The Hollywood Reporter. "It's a tough road, but I'm hanging in there."

Later, Kidman revealed the last words her mother said to her in an interview that aired on CBS Sunday Morning.

"The last words my mom said, which she didn't know were going to be the last words, were before I got on a plane and went back to see her," he shared earlier this month.

"She said to me, 'Maybe wait a minute because I think right now you need to take care of yourself, Nicky,'" he concluded.
