A group of New Zealanders, including Labour MP Kelvin Davis, is touring Australia to protest the cancellations of Kiwi visas under that country's tough immigration rules.
The Route 501 Hikoi, named after the section in the Migration Act, say they are visiting Australian cities to talk about the human rights issues surrounding the controversial clause.
Mr Davis, Labour's corrections spokesman, will be on board for the first few days of the tour, which began in Sydney on Thursday.
The group will visit all of Australia's major cities before flying to New Zealand to have meetings in Auckland and Wellington.
Visa cancellations are mandatory for anyone who is sentenced to 12 months or more imprisonment in Australia or have been convicted of any sexually-based crime against children.
The Ministry of Immigration and Border Protection can also cancel visas based on a character test.
