Good luck ! When I was in the NT on a paid safari recently the station owners were darting , capturing and selling their scrub bulls for good money . It was cheaper to shoot a representative buff bull than a scrubber .
Likewise there is money to be made from pigs in the top end . Some stations have helicopter shooting of pigs for meat export .Others have arrangements with safari operators and are paid for the game that is shot .
No offense intended but if you had access to a station that let you shoot pigs and scrubbers for free would you be sharing that info. on the internet ?
