I have heard, and understand, that in certain parts of the Pine trawlers are allowed to operate. On a recent trip with my neighbour, however, we were casting prawn nets in the hole just west of the bridge and local trawlermen were not amused. Turned their boat around and came right up behind us missing the back of our boat by less than two metres. Didn't have time to grab the mobile and take a photo.
Yes, it is hard for them to make a living and I don't object to them being there, but the river is for everyone to use and not put at risk this way.
