I agree, it is certainly no fault of APNIC but they were initially less than helpful when I advised them that we were having severe routing issues a week after the allocation was issued.
I have had a great response from users on the group and I appreciate everyone who has contacted me directly, you've all been a great help.

A bit of "spam" to operator lists isn't unreasonable for this sort of

We've that trouble a few times over the last couple of years, but I
don't think APNIC are at any fault at all for it. They send out
notifications about new address ranges they're going to allocate around
12 months in advance to a number of operator forums (I think this one
included). I think it's lazy sys/netadmins who are at fault - if they're
going to put these sorts of blackholing measures in place, they need to
fulfill the ongoing obligation they've created to keep the up to date.
If they're not going to do that, then they shouldn't cause trouble for
the rest of us by doing it in the first place.
