Frigatebird, They put up a fence but only across the area.....read useless.
They tried a combo of dried food then changed to wet food so they could put knockout drops in.......roos had a party then buggered off onto the runway to play. tried a weighted net gun thingy but greenies got upset about unduly harming hoppers. tried selective shoots but contracted shooters were so hamstrung with rules that they could not consistently shoot in good numbers. Tried shooing them out with a big line of ADF personal..failed.
I propose we induct them into the ADF and be done with it.
