One of the participants in our 2020 trip wrote a report about the trip for her bushwalking club. You can see it here.
Here is a link to a pamphlet about birdwatching put out by Tourism NT.
For several weeks at the end of the Dry (Kurrung) and beginning of the Build Up (Kunumeleng), the Mamukala billabong in Kakadu becomes home to tens of thousands of birds. The video clip here gives you a tiny taste of what it’s like. This is one of many places we will visit on this trip.
