At a whopping 30 metres high it is surely Queensland's largest landscape painting.

At the very least this mighty piece of graffiti art is now the pride of outback town Thallon, in the state's southern border region, population 450.

Created on four of the town's silos by veteran Brisbane street artists Travis Vinson [known as Drapl] and Joel Fergie [The Zookeeper], it took three weeks and 500 litres of paint to finish.

The pair, who used cherry-pickers to reach the high spots, say there is a burgeoning silo-art scene developing among graffiti artists and it is a movement that may soon need its own moniker.

"We're not really on the street anymore. There's definitely going to be a new term made for this sort of art," Mr Vinson said.



"It's a mural. But it's in a rural setting.



"I'm thinking rural mural, but that's a bit hard to say."

The artists worked with local photographers to create an iconic Thallon image with mustering sheep and birds perched on a gum tree near the Moonie River.



"It's hilarious, but after after being up there painting a landscape scene all day we go down to the river and soak up what we've been painting," Mr Fergie said.



The image is a peaceful scene, but Mr Fergie said when he was high up on the lifter and the wind started to blow, it was a less than peaceful feeling.



"I really don't like heights," he laughed.



"But when you work on something like this you know the reward at the end is going to outweigh any doubts you have in your mind.

"And I think after three weeks of being up high, I'm starting to get over that fear."

Western Queensland is known for its spectacular sunsets.



"People said 'Oh, did you exaggerate the colours of the sky?' But when you see a sunset out here, you'll see just how magical they are," Mr Fergie said.



"Out here the flat land really lights up just like this, and when the clouds are just right we're hoping to get a perfect shot that will be a continuation of what we've been working on straight through into the sunset."

The painting was finished in the middle of winter, the height of the grey nomad season.



"I reckon there's at least 50 caravans stopping each day to take photos," Mr Fergie said.



"It's really cool, because they'd probably keep driving to the next town if there wasn't such a beacon of light on the horizon."
