Elsa Pataky puts on a leggy display in a grey mini dress as she runs errands while her husband Chris Hemsworth arrives back in Byron Bay with their son Tristan

Elsa Pataky cut a stylish figure as she was spotted running errands before her husband Chris Hemsworth’s return to Byron Bay on Wednesday.

The Spanish actress, 48, was photographed stocking up on basics as she prepared to restock the fridges before Chris returned to their family home.

The next day, Thor actor Chris, 41, landed at Ballina Byron Airport via private jet with one of his twin sons Tristan, 10, as they arrived home after a mystery trip.

In preparation for their arrival, Elsa put on a very leggy show as she stepped out in a figure-hugging gray mini dress on Wednesday.

She showed off her toned legs in the chic ensemble and looked comfortable in a pair of white and pink sneakers.

Elsa added a pair of dark sunglasses to her golden locks as she carried her groceries from the supermarket to her car while running errands.

She was loaded with a carton of ginger ale, eggs and chips and other food items as she restocked the cupboards for Chris’s return.

On Thursday, Chris was then photographed landing at Ballina airport with his son Tristan as they prepared to reunite with Elsa.

The Hollywood icon looked travel-ready in a white T-shirt and baggy gray trousers, which he teamed with a pair of smart white trainers.

Chris kept a low profile, shielding his eyes from the bright sun with aviator glasses and wearing a black baseball cap.

Carrying his essentials in a black backpack, he was the doting dad through and through as he stepped out alongside his son Tristan.

Chris shares Tristan and his twin brother Sasha with his wife Elsa. They also have an older daughter India, 12.

The family lives in Byron Bay in a sprawling $30 million, eight-bedroom mansion set on a huge 4.2-acre plot of land in Broken Head.

But Elsa revealed she wasn’t always convinced about moving Down Under and had a very specific condition for Chris before she moved.

Elsa, who is originally from Madrid, admitted she told Chris she would only move to Australia if they lived on a sprawling farm where she could have horses.

“That was my deal with Chris,” she told the station Courier mail.

“I said I was going to move to Australia, but I wanted to live on an estate, a farm, and have horses, and he knew that.”

Elsa also gave a candid insight into her relationship with Chris and shared their secret to a happy marriage despite many challenges over the years.

“I think we all have this beautiful dream of marriage and loving each other and it’s all perfect, but it’s a lot more work than you think,” she said.

“It comes with so many challenges, but it’s wonderful to take on those challenges and learn about each other and how we change over the years and how we adapt to each other.

“You can think from the outside that a marriage is perfect, but they all have their stuff and they all need a lot of work.”

Elsa and Chris will celebrate their 14th wedding anniversary on December 22, although she admitted they rarely remember their anniversary.

Although it may seem like a misstep in the relationship, Elsa insisted the date is easy to forget because it is so close to Christmas, and said they laugh about it every year.

Elsa gushed about her husband and also admitted she always wanted a ‘partner for life’ as she opened up about how she wants to grow old with Thor actor Chris.

Elsa and Chris married in an impromptu ceremony while on holiday in Australia in December 2010, just three months after making their relationship public and ten months after first meeting.

They moved to Byron Bay five years later after buying their forever home in the coastal paradise for $7.6 million.
