Ningi is one of my favorite creeks in SEQ.
I basically only fish upstream of the ramp and usually about 2km upstream around the rocks there.
Very shallow to unpassable at low tide.
If you park yourself near the rocks for the bottom of the tide, have a rod ready with a tiny popper for the change of tide.
The place goes ballistic for 30 minutes with all of the fish hunting around the rocks in a feeding frenzy.
You will lose some lures yes but the rewards are outstanding action.
I was going to fish there this weekend but it is rained out by the forecast it seems.
Good luck Gaz.
