A Queensland family who lost their son and daughter-in-law in the disappearance of Malaysian flight MH370 have been hit by tragedy again with a family member on MH17.

George and Irene Burrows' son Rodney and wife Mary were on MH370 when it disappeared in March. Maree Rizk, from Sunbury, 40 kilometres north-west of Melbourne, who was one of 28 Australians killed on-board MH17, was the Burrows' step-granddaughter.

Mrs Rizk had been on a month-long holiday with her real-estate husband Albert Rizk and had reportedly tried to change their flight to avoid a long stop-over. The couple in their mid-50s, who had two children, were among 10 Victorians killed. Hume City councillor Jack Ogilvie said the community was in shock.

''We are all shaking our head in shock,'' he said. ''They were fantastic people. Albert was one of the guys who was always the life of the party.''

Seven West Australians were aboard, including sailor Nick Norris and his grandchildren, aged eight, 10 and 12. The four are believed to have been holidaying in Europe. Mr Norris, managing director of a Perth-based management consultancy company, was a frequent traveller to Europe for work. He was a member of the South Perth Yacht club.

''You always hear about these things and you always think about the poor people and families involved, but when it cuts close to home it's a lot more real and a lot more difficult to deal with,'' South Perth Yacht Club commodore Paul Ward said.

''Nick and Lindy were very active members of the club. Their children grew up through the club system.''

Nine people from Queensland were also on MH17 including Toowoomba doctors Roger and Jill Guard.

''Roger and Jill were so well known and had so many close friends throughout the city,'' Mike Horan, chairman of the Darling Downs Hospital and Health Service, said. ''There will be a lot of people who will be brokenhearted.''

Also among the Queensland victims was Gold Coast woman Helena Sidelik, who was returning from a holiday. ''We will truly miss your smiling and infectious personality that we have all become super fond of,'' her gym club manager Damien Glynn said.

Victorian teacher Frankie Davison from Toorak College and her husband Liam Davison were also among those confirmed on the flight. The couple had two children.

Former University of Melbourne student Elaine Teoh and her Dutch boyfriend Emiel Mahler were killed in the crash.

Ms Teoh, originally from Penang in Malaysia, and Mr Mahler, a Dutch national, were both 27. ''I urge my friends to remain wise and calm when talking about it and also keep my family and I in prayer as we are going through these tough times,'' her brother David Teoh Qu-en posted on Facebook.
