Forty crew remain missing including Australian man Lukas Orda and another unidentified Australian.

We remained in this place, called Syra Orda, about four weeks.

Mr Orda's wife Emma on Thursday night made an emotional post on social media.

M. Orda is the author of several elegantly-written pianoforte works.

Family and friends of 25-year-old Australian vet Lukas Orda are desperately hoping he will be found safe.

Mr Orda studied at James Cook University in Townsville before working at the Gold Coast Equine Clinic.

Such is the résumé of Carpini's observations made during his residence at Syra-Orda while he was awaiting the Emperor's election.

Liszt writes that Orda, "who seemed to command a future," was killed at the age of twenty in Algiers.

Davison mentions a M. Orda (the "M." stands, I suppose, for Monsieur) and Charles Filtsch as pupils of Chopin.]

The Department of Foreign Affairs and Trade are in contact with both Mr Orda's family and that of the other Australian crew member.

Lukas Orda's father said he was extraordinarily grateful for the search and rescue teams and he remained hopeful they would find the remaining crew members.

Queensland vet Lukas Orda, who is married with a six-month-old son, has been named as one of the Australians on board the missing cargo ship.

Lukas Orda was one of 43 crew members on-board the ill-fated Gulf Livestock 1, which was bound for China after leaving New Zealand last month.
