Recreation Lagoon

A sea wall designed to protect the entire site from a 1:100 storm surge captures a permanent body of water providing for swimming and other water-based activities.

Water is pumped in from the sea and the water quality is maintained through mechanical flushing and mixing.

Mesh screens are in place to prevent marine stingers entering the Lagoon, and there is a stinger net providing more protection on the beach side. Further, lifeguards regularly drag and monitor the water and night spotting for marine stingers is carried out frequently. But, while the Darwin Waterfront Corporation takes all reasonable steps to ensure the Lagoon is free of marine stingers we can not guarantee this.

A natural eco system exists including fish, algae, and Cassiopeia jellyfish. All play an important role maintaining a healthy environment. Large fish live in the Lagoon which at times have been known to brush up against swimmers. However, these large fish eat the jellyfish and we need them to keep the numbers down. If swimming with large fish isn’t the experience you are after then we encourage you to swim on the beach side of the stinger net, they are kept out of this area. Of course we will always monitor the situation and ask that people contact us if they have any concerns. Large fish are removed periodically.

As part of the Darwin Waterfront Corporation’s management plan water quality in the Lagoon is checked regularly.

Swimmers are not to go beyond the floating pontoon as that side is a construction site.

Fishing and feeding the fish in the Recreation Lagoon is prohibited.

The Recreation Lagoon is free to use and lifeguards patrol the water seven days a week between 9am – 6pm.


Like all outdoor activities the Wave and Recreation Lagoons are affected by weather.

From October to May wet season storms can pose a danger. Both lagoons will be evacuated if lightning is close by. If thunder is heard within 30 seconds or less after a lightning flash, lifeguards will evacuate both lagoons.

All swimmers and visitors need to leave the water and lagoon areas to seek shelter. The Wave and Recreation Lagoons will be re-opened once the storm has receded and thunder is heard 30 seconds or more after a flash of lightning.

For everyone’s safety listen to the lifeguard for instructions and obey immediately.

Shade is provided at the Wave and Recreation Lagoon and everyone is encouraged to be sun smart by wearing hats, using sun cream and drinking plenty of water – which are available from various retail outlets around the Precinct including the Wave Lagoon kiosk.

People are welcome to bring their own temporary, light-weight shade tents but nothing can be pegged into the ground without prior permission from the Darwin Waterfront Corporation.
