Unwilling relocation of hundreds of businesses that form part of the social and economic fabric of the local community.

Extremely shallow, variable water level will create an ideal environment for huge numbers of pest species - blue-green algae, water hyacinth, salvinia, cabomba, cane toads, mosquitoes, rodents, carp.
Decreased water flows to downstream communities and ecosystems- Gympie, Tiaro, Maryborough, Hervey Bay.
Uncertain effects on flood mitigation.
