An Aboriginal sovereignty campaigner says he is frustrated he was "hassled" by customs officers when he tried to enter Australia on an Aboriginal passport.

Callum Clayton-Dixon, who is the chairperson of the Aboriginal Provisional Government, said he was questioned for around 30 minutes on Friday evening when he arrived at the Brisbane International Airport from a trip to New Zealand.

He told ABC Radio he presented his Aboriginal passport but was told this was not a valid travel document.

An immigration official eventually confirmed through other means that he was an Australian citizen and allowed him through.

Mr Clayton-Dixon said the passport should be recognised by the Australian government.
The Aboriginal Provisional Government, which was established to fight for indigenous sovereignty, has issued several hundred of the passports since 1990.

Mr Clayton-Dixon said members have previously used it to enter countries like Norway, Sweden and Libya.

He said it was Aboriginal people's right to use it.

"We as Aboriginal people collectively have the fundamental human right as recognised by the United Nations to determine our own political independence and our own political status and the Aboriginal passport is a statement and an assertion of this right," he said.

In a statement, Customs said the Aboriginal passport was not a valid document but that if officials could verify that the bearer was legally allowed in Australia they would be granted entry.

Mr Clayton-Dixon said he would continue to use the passport on future trips.
