Good afternoon. The 14th of October will be the day Australians decide whether to recognise First Nations people in the constitution and create a voice to parliament to advise government on Indigenous affairs.

The prime minister announced the date and kicked off the yes campaign in Adelaide – a deliberate choice given South Australia is a key state that will influence the outcome of the referendum. Fresh polling shows the yes vote is slightly ahead in the state (43% yes, 39% no, 18% unsure).
