A man who allegedly rode a horse into an anti-Adani protester in Central Queensland on Sunday has been granted bail, with a warning from the magistrate.

Police alleged Clinton Morris McDonald, 41, entered the entertainment ring at the showgrounds on horseback about 3:30pm and struck a 61-year-old woman who was heading for a gate.

The woman was travelling in the Bob Brown Foundation's Stop Adani convoy, which held a rally yesterday in Clermont, and was flown to Mackay Base Hospital in a stable condition.

Mr McDonald was charged with "dangerous operation of a vehicle [namely a horse] causing grievous bodily harm", common assault, trespass and obstructing police.

He cried in the dock when he appeared in the Mackay Magistrates Court today.

The prosecution requested the defendant not be allowed to directly or indirectly make contact with the 61-year-old victim or any other stop-Adani protesters, including through social media.

Magistrate Athol Kennedy warned Mr McDonald not to answer any messages from unknown people on social media as stop-Adani protesters may try to bait him into contacting them and breaching bail.

The Stop Adani convoy was met with jeering and hostility by unions and locals when it arrived in Clermont on Saturday.

Bob Brown told reporters yesterday that some in his convoy were threatened by locals as they arrived into town, although police said no other arrests were made.

Isaac Region Mayor Anne Baker said the alleged actions of the rider didn't reflect the local community.

"We made it absolutely clear from the outset that disruptive behaviour from any party or person would not be tolerated," she said.

The Stop Adani convoy left Hobart almost two weeks ago, with hundreds of cars registered, and will now travel to Canberra for a final pre-election rally on May 5.

Outspoken Queensland political figures, like Matt Canavan, Pauline Hanson and Clive Palmer, gave speeches to the pro-Adani crowd in Clermont on Saturday.
