No jet lag here! Supermodel Elle MacPherson, 59, turns Sydney Airport into her own catwalk as she looks youthful with boyfriend Doyle Bramhall

Supermodel Elle MacPherson turned heads when she landed at Sydney Airport with her guitarist boyfriend Doyle Bramhall on Monday morning.

The 59-year-old looked incredibly youthful as she returned Down Under for the first time in four years to celebrate the 10th anniversary of her health brand WelleCo.

Elle cut a typically chic figure, wearing an all-white ensemble consisting of a pearl-embellished linen jacket and white trousers.

She paired her look with a matching scarf and black sunglasses.

The Australian star, also known as The Body, wore her blonde locks in beachy waves and appeared to be wearing minimal makeup.

Elle was seen holding hands with her guitarist beau Doyle, who looked equally stylish and matched the model, wearing a beige colored blazer and trousers which he paired with brown colored shoes.

The couple, who have been together for more than a year, appeared cheerful as they greeted several airport employees and waited for their luggage to be loaded into their waiting limousine.

Elle has attributed her ageless beauty to properly nourishing her body and supplementing with natural vitamins.

Elle shared on her Instagram Story an old interview of hers on NBC's Megyn Kelly Today, in which she discussed her diet and how she looks so flawless in her 50s.

“When I turned 50, I didn't feel or look very good,” Elle said.

'I noticed my skin, hair and weight…I just felt uninspired, I had sugar cravings and indigestion.'

She continued, “So I went to my nutritionist and said, listen, something is wrong, I need to address my lifestyle.

'She said I was taking a lot of synthetic vitamins, so she gave me a high-potency multivitamin, prebiotic and probiotic powder.

'So I started it because I was a bit malnourished and wasn't sleeping much, wasn't eating enough fruit and vegetables and was drinking too much coffee.'

She said that after following this new diet plan for a month and taking this natural multivitamin, her life was “transformed.”

'I saw such a change and my friend, who is now my CEO, said, “What are you doing, you look great?” and I told her that I used this green powder and it changed my life'.

Elle's dramatic transformation led her to start her own natural supplement company and wellness empire, WellCo.

This comes as the internationally renowned supermodel dropped the confession that she never enjoyed modeling but is grateful for the business opportunities it has brought her.

“I didn't like modeling but I love what modeling has given me,” she said on ITV's This Morning last May.

'I love creating images, producing and directing art and seeing magic come to life and it has been a wonderful means to an end for me because I travel, I am independent and therefore a great career.'

When asked if modeling has opened a lot of doors for her that she wouldn't have otherwise, Elle said, “I think it's about us stepping through those doors, being able to open those doors, but leaning into your heart, trusting your intuition and going “This feels good, I'm going to take a step towards it.”

Elle and Doyle were pictured at the Women of The Year Awards in Madrid on November 15
