The coastal zones along the Australian snubfin dolphin's range have been highly modified for mining and agricultural purposes as well as ports, aquaculture and residential development. Land reclamation, vessel traffic and construction results in the degradation of the snubfin's natural habitat through increased noise, lower water quality and a reduction in food supply, in addition to direct loss of habitat areas due to land reclamation. This can result in decreased survival rates and/or emigration in search of better resources.
