Jeremy Clarkson's giant, grey head has been doing the rounds in Sydney

Updated: 

To promote Jeremy Clarkson's new motoring show The Grand Tour, featuring fellow former Top Gear presenters James May and Richard Hammond, three giant heads have been travelling around Sydney.

The show is already up to episode four in the US, UK, Germany, Austria and Japan, but it is yet to launch in Australia.

People took to social media to share their photos of the giant, art-attack-style heads of Clarkson, May and Hammond.

A pretty confusing sight if you've no idea about the new show...

Following sightings in Washington State last week, it was reported that the giant heads were planned to be located next to the Space Needle in Seattle, but The Grand Tour twitter channel admitted that the plan hadn't quite worked out...

So the three eight-foot stone statues have been diverted through Sydney bearing Amazon and The Grand Tour logos.

The trio have been strapped to a lorry and driven between various locations in the Aussie city including Sydney Opera House and Harbour Bridge.

Amazon has not yet revealed the final destination of the statues, but trucks containing other body parts including arms, legs and crotches have also been spotted.
