We don't have holes at ours (BNE/YBBN) but there is an area with free car parking and a concrete pad on a raised area where you get a pretty good view, and can put a ladder to get an unobstructed view. If there's a really interesting aircraft movement you often get six or seven people with ladders and a whole bunch of others around.

Same at Sydney Airport (SYD/YSSY). There's even a guide with a map:
