The track down from Victoria Falls was closed for a while to allow for recovery after the bush fires. It now seems to be open - but be aware that the track probably has not had much use for a while - so could be indistinct in places and have fallen logs etc. Perhaps it has been re-cleared? The only official campsites mentioned in the plan of management are Burra Korain and Acacia Flat. Both are nice places. Acacia Flat is quite large - with two toilets. It can be popular on weekends - but even then - it is usually not too hard to find a site well away from other parties. At Acacia Flat - there are signs saying "Fuel Stove Only - No fires - Fines Apply", but according to the plan of management, there is only a trial on having no fires there. The NPWS website (
http://www.environment.nsw.gov.au/Natio ... x?id=N0004 ) makes no mention of the area being fuel stove only (I have camped there a fair bit over the years, and do use a stove, but I would estimate that most other parties do light fires). If you look on the website and see no reference to not having fires, then walk down there and see the sign "Fuel Stoves Only" then it is a bit far to go back home and get your stove!
The plan of management generally allows wild camping more or less anywhere in the park, within certain restrictions, such as distance from roads and limestone outcrops. But the Upper Grose Valley is mentioned as an exception and the plan states that "within the area of the Grose Valley upstream of Rocky Points Creek and below the cliff line" you must camp in "designated campsites". The plan also mentions "informal camping", and there seems plenty of evidence of this all along the Upper Grose. As well as Burra Korain, there are other quite nice campsites near the river, on the track between Crayfish Ck and Hat Hill Ck, another a few minutes before the junction with the Pierces Pass Track, another a little further downstream and Little Blue Gum (a great spot). For a Mt Victoria to Blackheath Walk via Blue Gum Forest, a camp at Little Blue Gum is about half way and a good choice. Also - as you walk out from Acacia Flat - on the track to Junction Rock, there is a nice campsite about 30 minutes upstream (just as you reach the creek again after the track climbs high above a large wash away).
If you do camp at Acacia Flat - then you can get good water if you dump your gear, and walk upstream about 5-7 minutes to a small side creek. It is normally flowing OK and has no pollution is its catchment area.
