The daughter of a Sydney woman arrested in Kuwait after arguing with immigration officials says security guards bashed her father and brothers.

Nasrah Alshamery, 43, has spent the last three weeks in jail and has been charged with allegedly insulting Kuwait's ruling emir, even though her daughter said she did not even know his name.

A Department of Foreign Affairs and Trade spokeswoman said consular staff had visited the family members in Kuwait.

"The Australian Ambassador to Kuwait has raised our concerns about these allegations at a senior level with Kuwaiti authorities," the spokeswoman said.

"The Ambassador has confirmed that Kuwaiti authorities are investigating these allegations and requested that he be notified of the outcome of this investigation when complete."
