8-9 Dec 2015, we went out and back to Mt Spec - plenty of water at Mac Springs (and Camp Creek, below Mt Spec).
However, although we didn't go to Hellfire Ck, I spoke to a guy who had just come from Mt Clear the day before (intending to camp at Hellfire Creek). Finding no water at Hellfire Creek, he pushed on to Mac Springs - adding about 5km to an already long day.
I know it rained all night of the 7th and most of the next day but the amount wasn't all that much. The small depression beside my tent was damp but no puddle. Since then, the BoM shows 11mm at Mt Buller on Sunday 20th.
Conclusion : probably some water at Hellfire Creek - but be prepared to push on to Mac Springs if necessary. It's a good walk in either direction and the saddle at Hellfire Ck is a great camp.
