Hey bud, the Hull is pretty big and I have followed it upstream for a few kms. The boat ramp is excellent and is the only one in the area with a plontoon. Fishing the hull can be hit and miss though (surprisingly for a big river). If you head upstream it forks off to the left and right. I think there are more options on the left side, hit the snags. But I will give you my #1 hint- you light gear with light jigheads eg gulpd prawns...even as light as 16lb leader..You may just pick up a few winter barra!....If you get good weather head out the mouth and troll for macks.....Be careful though as there are exposed sand bars in the river and lots of leather logs!
Hope this helps
