This post is an example of how information about a map marker can be included in the forums. If you go to the Sadgroves Creek, Darwin, NT, marker by Matt Flynn and click on it you will be returned to this forum thread, hence there is unlimited opportunity to link map markers to forum URLs and other web sites.

The edge of the mudflat out of Sadgroves Creek mouth is a great barramund spot from late Sept to Dec on a spring incoming tide. The fish will often feed on the first hour of the push in tide. Bait will move down the flat towards Darwin with the tidal current and predator fish follow - I have caught most species on the mangrove edge at half tide. Live bait is best, with lures working only on the barramundi.
