Im pretty sure all of Erindale Park was closed to fishing at one point because of garbage as was Port credit, and you still cant fish from the pier side.
The credit does get some religious "offerings" but i find theres way more garbage than coconuts.
I hate hearing people complianing about garbage, but never doing anything about it.
I filled 8 bags on the credit this past week and intend to fill a couple more.
As for the whole keeping fish thing, i think this thread was more about fishing spots being ruined by garbage and not fished out.
