Sometimes you don't eat meals for days, sometimes you walk for weeks - simply in order to do your work.
You're going to remote villages to deal with alcohol and marijuana-related problems, theft and the odd issue over refugees from across the nearby border with Indonesia.

He's been policing there for 20 years, and told Johnny Blades that accessibility is his biggest challenge, with no roads in the district and few telecommunications.
