The 31-year-old loosehead played four tests for the All Blacks in 2020 and qualifies for the Wallabies through his Fijian-Australian father after moving to the Queensland Reds this year.
Hodgman will become the first player in the professional era to represent both New Zealand and Australia if he takes the field at Sydney Football Stadium.
Following Australia's 2-0 series win over struggling Wales, new Wallabies coach Joe Schmidt has made 10 changes to the starting 15 that beat the Welsh 36-28 in Melbourne last Saturday.
They include uncapped winger Darby Lancaster, who played rugby sevens for Australia before picking up a contract at the now-defunct Melbourne Rebels this year.
In the teams' last meeting, Australia beat Georgia 35-15 in the group phase of the World Cup in France.
