Diane Hughes, 57, and her 65-year-old husband Ron were from Neston, Cheshire. They got married last year and were on holiday, Queensland Police said.
Their pilot and another passenger also died in Monday’s crash, which happened as one helicopter was taking off from a sandbar and the other was landing.
Three others, including two children, were badly injured and are in hospital.
In a statement to Australian news outlet 7NEWS, Mr. Hughes’ daughter Jane Manns said: “Our family is heartbroken and we are still trying to contact friends and family to let them know.
In a public Facebook post, Mrs. Hughes’ brother Dave Boyce thanked friends for their support, adding: “We are truly humbled at this heartbreaking time.”
Mr Hughes owned a home interiors company based in Neston on the Wirral peninsula, about 12 miles (18km) southwest of Liverpool.
