The culture wars between left and right rage across almost every issue - be it climate change, the economy, education, the arts - in social and traditional media daily.

Rockhampton roots-pop duo Busby Marou understand this conflict innately. Their native Central Queensland was at the epicentre of one of the most controversial issues at May's federal election - the Adani coal mine.

Many inner-city Sydney and Melbourne voters were vehemently opposed to the mine on environmental grounds, while the majority of Central Queenslanders were positive about the project's employment and economic benefits. Ultimately, the electorate voted for jobs.

It was in this intense political atmosphere that Thomas Busby and Jeremy Marou wrote and recorded their fourth album The Great Divide.

"There's so much going on and everyone knows it," Busby said. "There's so much fighting and everyone is complaining about everything.

"Whether you're for or against the issues, at the end of the day can we get through one day without us not liking each other?"

Busby Marou are perfectly placed to preach the wisdom of reaching out beyond our differences to find common ground.

"We come from two different walks of life and totally different cultures," Busby said. "Jeremy's a Torres Strait Islander, and I'm a white fella from Rocky and we're a big family and we've learned so much from each other over the years.

"I think we've both become better people and more understanding and we're more appreciative of different things like cultures or just decency and ethics.

"The Great Divide isn't about why everyone is so divided in the world, it's a celebration of two totally different stories. Two great divides can come together to make a colourful story and that's what we think Busby Marou is."

Busby Marou is also a story of amazing success. After toiling away on the blues and roots scene since 2007 and releasing their self-titled debut in 2010, the duo tasted commercial success when their 2013 record Farewell Fitzroy cracked the ARIA top five.

Then in 2017 album No.3 Postcards From The Shell House, led by the single Best Part Of Me and their breezy pop melodies and upbeat acoustic sound, landed Busby Marou a No.1.

The Great Divide, released last month, debuted at No.5. Busby admitted he felt nervous going into the album's release.

"We were told it doesn't happen for domestic acts anymore because of streaming and midweek we were looking at top 20 and I thought, 'OK it's definitely changed if that's the case', but to get top five was just crazy," he said.

"Music is never a competition, but just to know we're surrounded by all these international acts like Ed Sheeran, Taylor Swift and Post Malone is awesome."

For Busby, The Great Divide was also one of the most rewarding experiences of his recording career.

Holy Holy guitarist Oscar Dawson (Alex Lahey, Ali Barter) took up the production duties after the trio formed a tight friendship more than a year before recording commenced.

"It took us back to why we were doing it in the first place," he said. "There was no pressure. We laughed the whole time. We never took anything too serious.

"It was three people who knew how to write music. The combination was good. I know how to write music, Oscar definitely knows how to produce it, and Jeremy knows how to perform it."

Busby Marou will tour the album extensively throughout spring, before joining Cold Chisel on their Blood Moon Tour for shows in the Hunter Valley (January 18), Parramatta (January 24) and Wollongong (January 25).

Cold Chisel songwriter Don Walker co-wrote Luck with the duo on their second album Farewell Fitzroy, and Busby said it was an honour to finally support the pub rock legends.

"Just like everyone else in this country, Chisel are rock royalty to us," he said. "To be on a few of those shows is just incredible."
