A British family-of-five who were tragically killed when their seaplane crashed into a river north of Sydney on New Year's Eve have all been identified.
Millionaire CEO Richard Cousins was on-board the plane with his two sons, fiancee Emma Bowden and her 11-year-old daughter Heather when it plunged into the Hawkesbury River, north of Sydney, about 3.15pm on Sunday.
Mr Cousins' two sons Edward, 23, and William, 25, were also both killed in the accident, as was experienced pilot Gareth Morgan, 44.
The chief executive of British catering giant Compass, Mr Cousins was due to retire in March having spent the past 11 years at the helm and transforming a business on its knees to turning a £1.6billion annual profit.
It is believed he was in Australia on a family holiday to celebrate the New Year with his family when they died.

Paul Walsh, Compass chairman, said: 'We are deeply shocked and saddened by this terrible news.
'The thoughts of everyone at Compass are with Richard's family and friends, and we extend our deepest sympathies to them.
'It has been a great privilege to know Richard personally and to work with him for the last few years.
'Richard was known and respected for his great humanity and a no-nonsense style that transformed Compass into one of Britain's leading companies.'
