3 day Bogong High Plains hike

A group of us are planning a 3-day 2-night hike in the High plains area. Our idea is to...
Day 1: Falls creek up Heathy spur, Join AAWT and walk to Cope hut.
Day 2: Cope hut to Pole 333, and down Weston's to the Diamantina horse yards and camping area.
Day 3: Up Diamantina spur to Mt Feathertop and then across razorback to Hotham.
We are aware that Diamantina spur is steep but we are prepared and have done previous hikes around Mt Feathertop before. We will most likely be going 27-29 September.
Haven't found too much information on it but is the area near Diamantina horse yards suitable to camp?
Any advice or information would be greatly appreciated.
Edit** Most likely go Cope hut to Fed hut in the one day. Then feathertop to hotham last day.
