Footage shows huge flames erupting from methane gas bubbling to the surface of the Condamine River, a result of ongoing coal seam gas mining in the region, some locals say.

Large bubbles of the gas gurgle along the surface of the river before Greens MP Jeremy Buckingham waves a kitchen lighter over the side of a tinny boat.

Without warning the river explodes in flames, forcing Buckingham to retreat to the opposite side of the boat.

The flames continue to burn throughout several minutes of footage posted to the MP's Facebook page.
