Parasites are integral yet overlooked components of marine ecosystems, reflecting host ecology, trophic interactions, and environmental conditions. Despite this, parasite community structure in Australian coastal dolphins remains poorly resolved. This study provides the first quantitative, community-level assessment of parasite assemblages in the Indo-Pacific bottlenose dolphin (Tursiops aduncus) from Southeast Queensland (SEQ). Parasites were recovered from stranded and bycaught individuals via systematic necropsy and identified to the lowest possible taxonomic level using morphological techniques, with molecular confirmation where required. Standard parasitological metrics, including prevalence, mean intensity, mean abundance, and species richness, were quantified. Variation in parasite assemblages was examined across organ systems, host-level factors (age class, sex, body condition), and regions of SEQ using generalised linear models and non-metric multidimensional scaling. Preliminary results indicate assemblages dominated by nematodes, including Anisakidae spp., with additional helminths including respiratory nematodes, Halocercus spp., and gastric trematodes. Parasites were primarily recovered from the gastrointestinal and respiratory systems, with highest burdens in the stomach and lungs. Organ-specific assemblages indicate strong tissue tropism consistent with parasite life-history strategies. The presence of trophically transmitted taxa suggests infection pathways linked to fish and cephalopod prey. This study establishes the first quantitative, organ-specific baseline for parasite community structure in T. aduncus in SEQ and provides insight into host–parasite dynamics, trophic connectivity, and coastal ecosystem processes, supporting future comparative and long-term studies in Australian marine systems.
