Yes mate,
With fishing you've got to take the good with the bad.
In regards to fishing PNG I've been lucky enough to have been on half a dozen good trips - all worthwhile. Once you get to experience a trip there you can't help thinking about when the next one will be.
My recent Lake Murray trip I organised ex-Bris but the previous five I arranged locally with the fishing club I was in when I was based in PNG (2004-07).
I'll be back there for sure at some point in the future.
One time, when fishing at Suki and we were hanging out to catch a barra for the evening barby. But the black bass were hot! We were hooking up nearly every second or third cast and looking at each other saying, "Ooh geeze, not another bass..!" It was great fun and eventually someone did catch dinner for us.
The only parts of PNG I have fished have been in the Western Province (Fly River / Lake Murray). But as you can see from some of the fishing shows on tele you can also get bass (mostly spot tail) on some of the larger islands, like New Britain in the east.
But places like Suki & Lake Murray are unique as you can catch Barra/Black Bass/Saratoga/Tarpon & Catfish all in the same location.
"...A voice in my head told me I had to go fishing..!"
