But former Greens leader Bob Brown says his anti-Adani convoy still has another week of campaigning left in it.

The group is expected to leave the central Queensland town of Clermont on Monday after a weekend which saw many businesses shun those opposed to the proposed Carmichael mine site, which is more than 170km from the town.

Clermont's three pubs refused to serve the visitors and a sign was hung from a hotel 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".

Grand Hotel publican Kel Appleton, told AAP the town felt it had to organise a response to the protesters by shunning the convoy.

He said many in Clermont supported the proposed mine and the jobs it is expected to bring the region.

"We still get treated we're like a bunch of hooligans but we're not, like I'm half proud of being called a redneck, we probably are, we live out west, there's graziers, there's cotton farmers," Mr Appleton said.

Following the convoy's hostile reception, police received reports shots had been fired in the town. These were later suspected to have been firecrackers.

While supporters are worried about missing out on jobs if the mine doesn't go ahead, Mr Brown claimed the "jobs alarm" was greater on his side of the debate, referring to 64 thousand jobs on the Great Barrier Reef, that were threatened by new coal mines.

Asked how the proposed mine was a threat to the reef Mr Brown said: "the mine is symbolic of that dying process (the burning of fossil fuels) continuing".

"Stopping the mine is symbolic of we human beings having the common sense and good grace to go to the cheaper alternative of renewable energy."

Mr Brown said the convoy wasn't finished and would continue to arrive at Parliament House in Canberra next Sunday.
