Cathedral Plateau

Has anyone walked from Junction Hut up onto Cathedral Plateau
via Chalice Lake and down into Lees Paddocks?
if so - how long do I need to allow to cover this distance?
Are there any walking tracks over or through Cathedral Plateau?
Does anyone have information concerning Hartnett Track which I believe
descends between Bishop Peak and Curate Bluff? - roseart
