- Never dump fish, plants or snails into or near waterways, stormwater drains or the ocean. This is illegal and penalties apply.
- Don't keep noxious species in your fish tank.
- Don't buy fish, plants or 'live rock' from overseas on the internet - it's illegal. Use a reputable local dealer.
- Take care cleaning tanks or ponds. Tip waste water on the garden. Place solid waste like plants or gravel in the bin, or bury them.
- Design fishponds so that plants, snails, fish or eggs can't escape during heavy rains, and screen all overflow areas. Consider keeping species native to your local area.
- Look out for new species in local waterways. Report suspected pests to NSW DPI's 24 hour hotline: 02 4916 3877
