Madeline Holtznagel celebrated turning 26 in style over the weekend.

On Saturday, the model - alongside her billionaire pub baron boyfriend Justin Hemmes, 49, and her sister Simone, 28 - was spotted arriving to Vaucluse via a seaplane before heading to his $60million mansion for an epic pool party.

The trio, joined by an abundance of their pals, had already enjoyed a luxurious meal of oysters, caviar shots and birthday cake at Merivale boss Hemmes' Newport restaurant Bert's Bar and Brasserie earlier in the day.

In photographs from the landing site in Vaucluse, Madeline was seen being pick-backed across the water by the plane's captain to avoid getting her glamorous ensemble wet. 

She looked absolutely stunning in a thigh-flashing floral dress, which she teamed with a pair of slip-on sandals.

Madeline, who was seen holding hands with her boyfriend as they walked across the beach, accessorised with a $2450 YSL bag and styled her hair in a trendy bun.

She wore just a touch of makeup to enhance her naturally striking features, including a pretty pink gloss and a flash of bronzer and highlighter across her cheeks.

Madeline's sister Simone looked equally as beautiful as her sister in a stunning patterned dress, which showed off her epic curves and toned arms to perfection.

As she exited the water, Simone was seen wrapping the long gown just above her thigh, while carrying a pair of heels in her hand.

She wore her long, luscious locks in a gentle beach wave, and donned a pair of oversized sunglasses for the occasion.

It's love! Madeline also shared a picture kissing her boyfriend in their party clothes to commemorate the big day
