a secret ballot provided at public expense

Explanation:

In 1856, a secret ballot law was passed in the state of Victoria in southeastern Australia, according to which, at the expense of the state, a single ballot should be printed for all candidates. It also left space for the voter to enter the name of any other candidate. The "Australian ballot" has been used in the United States since 1888. The "Australian ballot" is synonymous with the term "secret ballot."
