Marilou Danley's sisters have said they believe she was "sent away" so she could not interfere with her boyfriend's plan to open-fire on thousands of people in the Las Vegas massacre.

Ms Danley, 62, touched down at Los Angeles Airport on Tuesday night and was escorted by the FBI who said they "have a lot of questions" after Stephen Paddock executed the sniper attack.

Speaking exclusively to Seven News, the Australian woman's sisters said they were in complete shock to discover their sister had arrived in the Philippines two weeks ago.

"I know that she doesn't know anything as well like us," one of the sisters, who chose to remain anonymous, said.
