So you have completed the Adventure Lab, NRRT Mooball. Congratulations !
You willl have been given the corrected co-ordinates after doing the final location of the Adventure Lab.
While in Mooball, have a look around and imagine what it was like in its heyday when the railway line was there.
The Mooball Railway Station closed in 1974 however the railway line which went further north to Murwillumbah closed in 2004.
