Melbourne Cup: Jackson and Brooke Warne attend with partners

Jackson and Brooke Warne were the spitting image of their late father Shane as they arrived at the Melbourne Cup on Tuesday.

The siblings dressed down to the last detail for the race that stops the nation at Flemington Racecourse, along with their respective partners Kiah Broadsmith and Alex Heath.

Jackson, 23, wore an off-white suit over a white shirt and adorned with a matching black tie, belt and suede shoes.

The professional poker player was all smiles with his girlfriend on his arm, while Kiah stunned in an elegant one-shoulder dress.

Meanwhile, Brooke, 25, turned heads in a chic red trouser suit over a black satin blouse, which she paired with black heels, a chunky headband and silver jewelry.

To tie the look together, she wore a $4,300 Louis Vuitton handbag and opted for a neutral makeup look while pulling her blonde hair back into a low ponytail.

Her boyfriend Alex, with whom she has been in a relationship for six years, looked just as fashionable in a navy checked suit and brown dress shoes.

Brooke’s outing with her brother comes after she revealed she was struggling with her mental health following Channel Nine’s announcement that a biopic will be made about her late father Shane, against the wishes of the family.

While attending a non-profit gala in Melbourne to promote awareness for both mental health support and suicide prevention, she told the Herald Sun that her involvement with the charity helped her make the network’s decision.

“With the added media attention brought on by father’s passing, I have to remain vigilant to deal with the attention,” she explained.

“Especially on the negative side, like the total disrespect Channel Nine showed in making a biopic about Dad so soon after he died.”

Brooke had previously labeled Nine’s decision to make a telefilm based on her father — just months after he died — as “more than disrespectful.”

Brooke took to Instagram last month and asked the network’s bosses, “Do any of you have any respect for Dad? Or his family?

“He’s done so much for Channel Nine and now you want to dramatize his life and that of our family six months after his death?”

After backlash from the Warne family, Nine entered into “crisis” conversations about the film.

The outing comes after Brooke said she struggled with Channel Nine’s announcement that it will be doing a biopic about her late father Shane, against the wishes of the family.
