Hi Rob

The exact length of flag polls for each range is not something I can answer but I use the BRT flags which have extentions pieces and it serves me well for most ranges. I have 6 flags in all, two polls are very short  and I recall using the short polls at Canberra last year for close up to the bench, I have a selection of short and long tails as well as different tails for light or windy conditions. ie Standard BRT flag tail for moderate to windy and surveyers tape for very light conditions.
Batemans Bay requires longer polls and while I don't have the really long ones, I do extend my polls by another 4ft above their max (Dowell from Bunnings works fine) - 4ft polls fit nicely in the boot of my car, but if I had more room than would have made them longer.
Not sure about the other ranges you mention, but hopefully other shooters can chip in here.

Good shooting,

Dave
