Special helmets that accommodate turbans and uniforms incorporating burkas are part of a push to build a more diverse Australian Army.
Army chiefs are hoping to attract bigger numbers of multicultural recruits, especially those of Arabic and Indian descent.
Among the changes being considered are specially designed helmets that fit turbans worn by Sikhs.
Army Commodore Tim Barrett, director of recruiting, said the army wanted to change community perceptions that it was intolerant of some nationalities.
An advertising campaign would begin next month with defence members from non-English-speaking backgrounds encouraging others to join, he said.
"We are looking particularly at Indian and Arabic communities," he said.
