A Bob Brown-led convoy to stop Adani’s Bowen Basin mine has been greeted by hundreds of counter-protesters as it arrived in Clermon in the heart of the coal-rich Queensland region.

And the heckling didn’t stop when the sun down, with the anti-coal caravaners’ slumber disturbed by fireworks tossed into their camping site.

One explosion spooked travellers into calling police just before midnight to report a suspected gunshot.

But a police spokeswoman said there was no evidence of a shot having been fired, with officers working on the assumption that it was aother firework.

”There were a few firecrackers over the fence in the middle of the night, but everybody had a cracker of a night,” Mr Brown quipped.

The convoy of about 400 mine opponents reached the mining town of Clermont on Saturday afternoon after politicians Matt Canavan, Clive Palmer, Pauline Hanson and Malcolm Roberts arrived earlier to support the coal industry.

Residents lined the main street and jeered as the convoy, comprising around 200 cars, rolled down the main street.

Mr Brown, the former Australian Greens leader, has urged coal advocates to “use your God-given intelligence” to stop the “worsening climate emergency due to the burning of fossil fuels”.

“It’s a complete fabrication that people in central Queensland aren’t worried about this mine,” he told AAP ahead of his arrival.

“We should all be committed to putting the aggression to one side and talking about the issues, the key issue being the future of our children.”

Local publican Kel Applegate organised the rally in support of the Adani project, saying visitors would also struggle to find a beer after Clermont’s three pubs agreed not to serve them.

Mr Appleton, a protest opponent, told AAP the town felt it had to organise a response to the protesters by shunning the convoy.

“It’s nothing personal but (the anti-Adani activists) are hypocrites,” Mr Applegate told AAP.

“How do they think steel gets made, or their electric trains run? It doesn’t come from solar panels or wind farms.”

Clermont’s three pubs refused to serve the visitors, with one sporting a sign hung from its balcony which read, “Go home and turn off your power and walk”.

Another read, “Mr Brown and ‘Stop Adani’ protesters, you may have travelled far and wide but you won’t get food inside”.

“We’re just normal people, we don’t go pushing our rhetoric on anyone else like they do to us.” Mr Appleton said.

Mr Brown said his “law-abiding and peaceful” convoy faced a “gaggle” of right-wing politicians as part of the “festival of democracy”, but his message would otherwise be welcomed.

“I was braced for a hostile reception in Mackay and it turned out it was mega-friendly,” he said.

He reiterated a claim a disabled member of his convoy had been “punched” in a display of “alcohol-infused thuggery by some pro-Adani people.”

State shadow mining minister Dale Last, also in Clermont, said residents were “very angry that this group’s coming out here to tell them what they should and shouldn’t be doing.”

“I think these protesters will be left in no doubt they’ve walked into a hornet’s nest in this country,” he said.

“They’re going to get a very, very hostile reception, I can assure you of that.”
