Foster was vocal in campaigning on behalf of Bahraini footballer Hakeem al-Araibi, who was granted protection as a political refugee in Australia in 2014 but was detained upon arrival in Thailand in November 2018 while on his honeymoon with his wife owing to an Interpol red notice put out by Bahrain. Foster travelled to Switzerland to present a petition with more than 50,000 signatures demanding the release of the detained footballer and held talks with general secretary Fatma Samoura FIFA on 29 January 2019, spent time in Thailand speaking to al-Araibi's legal team and visited al-Araibi in prison. Foster's many tweets on the topic were widely shared. After al-Araibi's release was secured, others tweeted nominations for Foster as Australian of the Year or even prime minister. Many politicians, including current prime minister Scott Morrison praised him for his efforts.
