Just finished speaking with PV. Good news. Rosea climbing area is open for climbing! They have agreed that as we only need to use a small section of the walking track at the start then this will be acceptable in order for us to access the climbers track. Please note though that the Rosea walking track is still officially closed so don't use this to access any other part of the area. Other users are still not able to use it and the area and walking track won't be promoted.
I assured them that it is highly unlikely that the climbers will want to be doing anything other than walking up the climbers track and climbing :)
