Popham Bay is a significant estuarine system on the Cobourg Peninsula within Australia's Northern Territory. It forms a major part of the Cobourg Marine Park and is a gateway to the Van Diemen Gulf, known for its pristine, remote waters. The bay serves as a protected anchorage and a renowned jumping-off point for anglers and boaters heading through Dundas Strait and around Cape Don. Its waters are part of a vast marine sanctuary, contributing to its reputation for high-quality, relatively untouched sport fishing opportunities in a spectacular Arnhem Land setting.

Key areas focus on tidal flow and structure. The tide ripplings and current seams approximately two miles offshore from the bay, noted in historical records, are classic spots where baitfish get pushed to the surface, attracting larger predators. The channels leading from the bay out toward Cape Don and into Dundas Strait are prime corridors for pelagic species. The mangrove fringes and estuary mouths within the bay itself hold fish on the higher tides.

Northern Territory Stream Access Laws

NT has no single generic stream-access statute; the major access consideration is that much of the NT's intertidal waters overlie Aboriginal land. Permission is required to enter intertidal waters over Aboriginal land, and recreational fishers must register (via the Northern Land Council) to access some waters.
