The Australian Cricket Board has launched a public appeal to purchase the cap Sir Donald Bradman wore in his last Test appearance in 1948.
The cap has been in Britain for the past 47 years after Bradman gave it away to his English godson, but will be auctioned in July.
The ACB and an Australian newspaper group have joined forces to try and buy the baggy green cap and bring it back to the country.
ACB chairman Bob Merriman said the cap would be put on display in an Australian museum.
