Mt Field - Tenting around Lake Dobson

Taking a uni group of to Mt Field on the weekend and wondering if there is any reasonable (+ free) tent sites around the general Lake Dobson/Eagle tarn area.
Potentially getting there late-ish and don't want to be floundering around looking for an area. Looking at up to 4 2P tents.
Normally I would just wing it with a tent and walk in the dark if I had too but thats not the best approach in this situation...
Thanks
