A university student accused of racial discrimination over a Facebook post has amassed a hefty legal bill, which could blow out to $200,000 if the case goes to trial.

Alex Wood is being sued under the Racial Discrimination Act over a 2013 post he wrote after being asked to leave a Queensland University of Technology computer lab reserved for the use of Indigenous students.

"Just got kicked out of the unsigned Indigenous computer room. QUT is stopping segregation with segregation," he posted on a Facebook page called QUT Stalker Space.

The post attracted comments critical of both the incident and the existence of the Indigenous-only space.
