Invasive aquatic animals

Introducting invasive animals into the Gold Coast’s natural waterways and wetlands can negatively affect native fish biodiversity and abundance. Impacts include:

• competition for food and space
• introduction of parasites and diseases
• loss of native species and decreasing native fish populations
• habitat alteration that can negatively impact waterways.

In Queensland, it is illegal to release noxious or non-native fish into our natural waterways. To learn more visit Queensland Government's Biosecurity webpage.

What you can do

• Choose native fish rather than exotic species.
• Keep aquarium collections in secure ponds.
• Trade unwanted fish and plants with aquariums, pet shops or fish auctions.
• Never dispose of aquarium collections within our natural waterways or lake systems.
• Do not release exotic species back into a waterway if you catch them while fishing.
• Learn more about invasive or high-risk fish,
• Get involved in free NaturallyGC activities.
