great post bunya.
used to live up that way and everything you say is correct.
They will still be using the sump oil on every fence post beleive me.
When i was there just five years ago the farmers also used a product called "edb" the enviro's banned it ( this got plouged into the ground by the way)but they could still use what they had left. i know some that still have a couple of years supply left.
