The Federal Government's outbound travel ban will be challenged in federal court by LibertyWorks - a conservative non-profit group.
The group launched legal action against Australia’s travel ban in December last year, arguing it is a breach of fundamental human rights.
LibertyWorks representatives said inbound passengers could remain while outbound travelers could be made aware that leaving Australia does not guarantee a return.
"We are aware of people missing funerals of loved ones, others being unable to leave Australia and care for sick relatives, couples that have been separated and cannot reunite, the birth of children with the father," LibertyWorks president Andrew Cooper said in a statement on Wednesday.
The case is to be heard by the full bench of the Federal Court today.
