Justin Hemmes, 48, takes his girlfriend, 24, for a ride in his private seaplane

He famously bought a seaplane in 2016 to beat the morning traffic on his daily commute in Sydney.

And Justin Hemmes was spotted boarding the plane outside his harbourfront estate in Vaucluse on Tuesday.

The billionaire pub baron, 48, was joined by his much younger girlfriend, model Madeline Holtznagel, 24, for the flight.

The hotelier dressed casually for the outing in tan pants and a white T-shirt.

He went barefoot and slung a duffel bag over his shoulder as he crossed the beach.

The father of two styled his wavy blond hair in a man bun.

Justin made the high-flying purchase so he could cut down his 94-minute daily commute to just six minutes.

He now flies from his mansion in Vaucluse to his office in Newport instead of driving.

Justin’s hospitality empire is believed to be worth about $1billion. 

He and Madeline have been spotted out and about in Sydney several times lately, after confirming their romance.

Madeline lifted the lid on their relationship in October, telling The Sydney Morning Herald she was yet to introduce Justin to her parents.

‘My parents and my sister Anna haven’t met him yet, but [her other sister] Simone has been introduced to him and really liked him,’ she said.  

Madeline remained tight-lipped about how long she and Justin had been dating, but hinted they’d been seeing each other for longer than reports suggested.

‘We have known each other for two years and met when I was modelling in Singapore,’ Madeline said.

The couple sparked romance rumours when they were spotted partying together on his Bombardier Challenger jet last August.
