Sydney Seaplanes (Sydney Kingsford Smith) has suspended all flight operations following the crash of a De Havilland Canada DHC-2 on December 31, 2017, that killed all five passengers and one pilot on-board.

Floatplane VH-NOO (msn 1535) was taking off from Cottage Point for Rose Bay Water Airport when it reportedly turned sharply to the right before crashing into Jerusalem Bay.

Managing Director Aaron Shaw told a press conference that all operations had since been suspended until further notice.

"We do not yet know the cause of the accident. We are dedicating our full resources in assisting the NSW Police, the Australian Transport Safety Bureau, Civil Aviation Safety Authority and other relevant authorities to understand the cause of the accident," he said.

Founded in 2005, Sydney Seaplanes also operates another Beaver as well as one Cessna (single piston) 206H and one Cessna (single turboprop) 208 Caravan.
