"It's a awful situation for these people that were on holiday", Inspector Steve O'Connell said.
Her condolences came as the Queensland Government is resisting calls to install drum lines in Cid Harbour following a fatal shark attack yesterday, the third attack in the same area in two months.

Reports of operators dumping scraps over the sides of boats, which could be exacerbating shark activity in the area, will be discussed at the roundtable.
