The Cato River is a tidal estuary system flowing into Arnhem Bay within the remote East Arnhem Land region of Australia's Northern Territory. This fertile riverine environment is situated on Aboriginal land and offers a culturally immersive and adventurous fishing experience characterized by its pristine, undeveloped landscape and significant populations of iconic Australian sportfish. Access is managed through a traditional owner-run camping operation and requires specific permits, emphasizing the importance of respecting Indigenous land rights and protocols. The river's environment presents unique challenges, including extreme tropical heat, humidity, and the ever-present danger of large saltwater crocodiles, demanding careful planning and vigilance from visiting anglers.

Northern Territory Fishing Regulations
Official NT page setting recreational possession limits, including a general personal possession limit, separate limits for exempt species, and per-vessel limits. See the page for current numbers.
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.
