Interesting watching the Mt Airlie video and seeing how the track has changed. Quick screen grab from the video in here from 2013 and a video from a month or so ago.
This is the last step, the JKU's stuggled due to bottoming out. The step is undercut now, the hole in the middle is bigger, even a point on the rock that made the climb easier has gone altogether and a lot of the soil to the left where an easier line was has gone. Rest of the track is looking harder than it was in 2013 as well.
Cheers
