@blaxland fishraider where we are right now IS a really big well organised facebook.
The quality info sits here for many, many, many people over many years.
I too am on tons of Facebook groups but they don’t give me the info I find on fishraider. Do a google search and usually a fishraider post comes up with the answer.
By the way there is a fishraider page on Facebook
You are free to start a fishing group on Facebook but it would not be an official page. We would be unable to commit to its moderation.
