In reply to Paul Troon:
In my experience Wye Ck is the only place that might qualify as 'reliable' for climbable ice, and even then it's pretty limited compared to any overseas venue. It's a solid 2hr snowshoe or ski from the parking area at The Remarkables ski field. There's usually beta at least, on what is in, or not.
I've done two trips into Bush Stream when it was in good conditions and I think it's better than Wye Ck. Both times I have helicoptered in, stayed a couple of nights and walked out. It's about 4hrs out to the road, but not much of a track. It gets some avo danger, but not extreme and there's a better selection of lower grade (WI3ish) routes than Wye, as well as longer harder routes. Wye has better access to steeper routes though, if that's what you want.
In terms of reliability, I think there will always be something climbable in at Bush Stream in a normally cold July-August, but it will vary. You can see the top of one of the main WI5 routes from the road, just, so that gives you some idea before you commit.
