Australian Seabird & Turtle Rescue (ASTR) recorded 763 wildlife rescues across the Northern Rivers in two years; 95 (12.5%) involved marine-debris entanglement. We ask whether beaches with the most rescues also contain microplastics that may create an additional exposure pathway. We hypothesize that microplastics will occur at all selected rescue hotspots, with greater abundance near estuary outflows and human activity. Fortnightly sampling will identify potential exposure hotspots.
