Jonah Hill may only have made a cameo appearance in Django Unchained, but it was long enough for him to make an impression on co-star Leonardo DiCaprio.

The unlikely pair were spotted hitching a ride on a luxury yacht together on Saturday afternoon in Sydney.

And in a show of solidarity, Jonah undertook Leo's signature off-duty look by wearing a baseball cap too.

Saying that, the searing Australian sun beating down upon the two may have had something to do with the 21 Jump Street star's headwear, but the heat mustn't have been to unbearable as Jonah wore a denim shirt over the top of a T-shirt.

Leo was his typically casual self in a faded blue T-shirt, cargo shorts and deck shoes, which in all fairness is the most suitable outfit for the watery excursion.

However, an orange and white package tucked under the 38-year old's arm begged the question: what was in the package?

The carrier seemed to have 'The Darling' printed on it, which could be the name of the hotel Leo and Jonah were staying at, so may well have been filled up with a few complimentary toiletries to take on the yacht, just in case there's a moisturising emergency.

The hotel, conveniently offers luxury hotel rooms and stunning views from the Sydney Harbour Bridge, so it's the perfect location for a quick boating trip.

As the ship embarked on its scenic route which offered sights like the world famous Sydney Opera House, Leo was spotted chatting to a gaggle of girls.

Whether they had arrived with or separately from the actors isn't known, but they no doubt enjoyed the rest of the boat trip in close proximity.

However as the Wolf On Wolf Street star is rumoured to be dating former Neighbour's actress Margot Robbie - they met on the New York set of the aforementioned movie - maybe the female company was more for Jonah's benefit.

Their presence in Sydney is reported to be part of a New Year's party to rival any other.

A slew of celebrities - including Jamie Foxx, Chace Crawford and DJ Samantha Ronson - flew into Sydney with Leo on Friday, to welcome in 2013 in Sydney before heading back to the U.S, more specifically, Las Vegas for round two of New year antics.
