Who is a refugee?
The 1951 Convention Relating to the Status of Refugees (and its 1967 Protocol), to which Australia is a signatory, defines a refugee as:
Any person who owing to a well founded fear of being persecuted for reasons of race, religion, nationality, membership of a particular social group or political opinion, is outside the country of his/her nationality and is unable, or owing to such fear, is unwilling to avail himself/herself of the protection of that country.
