A 30-year Brisbane taxi industry veteran has bragged of bashing an Uber driver in a social media post and encouraged others in the industry to "get more militant" and do the same.

Greg Collins, the owner of the Virginia-based cab company Complete Taxi Management, admitted on the Brisbane Taxi Driver Facebook page on Sunday that he had physically assaulted an Uber driver, as the war between the industry and the ride-sharing app's drivers escalates.

"F---ing slap him like I did to the prick in Warner St the other night, I am f---ing over them. You wait I will f---ing get them. They won't and can't defend themselves they are illegal. If it was 30 years ago in my time, they wouldn't last five minutes," he wrote, in response to a post by a taxi driver who claimed to have been assaulted by an Uber driver while trying to take his photo.
