As I hate to see people demonised as a result of ignorance, I am reproducing the following from the SBS website in an effort to help allay some misunderstandings:
Asylum seekers who arrive in Australia by boat are neither engaging in illegal activity, nor are they immigrants. The UN Refugee Convention (to which Australia is a signatory) recognises that refugees have a right to enter a country for the purposes of seeking asylum, regardless of how they arrive or whether they hold valid travel or identity documents.
The Convention stipulates that what would usually be considered as illegal actions (e.g. entering a country without a visa) should not be treated as illegal if a person is seeking asylum. This means that it is incorrect to refer to asylum seekers who arrive without authorisation as “illegal”, as they in fact have a right to enter Australia to seek asylum.
In line with our obligations under the Convention, Australian law also permits unauthorised entry into Australia for the purposes of seeking asylum. Asylum seekers do not break any Australian laws simply by arriving on boats or without authorisation.
Australian and international law make these allowances because it is not always safe or practicable for asylum seekers to obtain travel documents or travel through authorised channels.
Refugees are, by definition, persons fleeing persecution and in most cases are being persecuted by their own government. It is often too dangerous for refugees to apply for a passport or exit visa or approach an Australian Embassy for a visa, as such actions could put their lives, and the lives of their families, at risk.
Refugees may also be forced to flee with little notice due to rapidly deteriorating situations and do not have time to apply for travel documents or arrange travel through authorised channels. Permitting asylum seekers to enter a country without travel documents is similar to allowing ambulance drivers to exceed the speed limit in an emergency – the action would ordinarily be considered illegal, but the circumstances warrant an exception.
It is also incorrect to refer to asylum seekers as migrants. A migrant is someone who chooses to leave their country to seek a better life. They make a conscious choice to leave and they can return whenever they like. Refugees are forced to leave their country and cannot return unless the situation that forced them to leave improves. Some are forced to flee without warning; significant numbers of them have suffered torture and trauma. The concerns of refugees are human rights and safety, not economic advantage.
