Locals in the coal mining towns of Mackay, Rockhampton and Clermont are not planning a warm welcome when Bob Brown's "Stop Adani" convoy comes into town next week.

With Adani's controversial $2 billion Carmichael mine still a sensitive issue in regional seats across Queensland, the former Greens leader's convoy of up to 770 cars protesting against the mine is expected to stir things up ahead of next month's election campaign.
