Samoa's district court has convicted Talalelei Pauga of making false declaration to his arrival card and ordered him to pay a fine of $US1200.
Today's sentencing came after Pauga admitted the offence under Samoa's Immigration Act on Thursday.
A police source revealed Pauga had previously been fined in Australia on a public nuisance charge.
In Brisbane last year Pauga last year threw a pig's head at Tuilaepa Sa'ilele Malielegaoi, claiming the prime minister was ignoring issues that were important to the people.
In that matter he was discharged without conviction.
