The spelling of "regularization" in Australia is the same as in other English-speaking countries, with one "z" in the word: regularization.

To write a letter of regularization, address it to the appropriate person or department, clearly state your request for regularization of employment status, provide details on why you are seeking regularization (e.g., completion of probation period), and highlight any relevant achievements or contributions. Express gratitude for the opportunity and end the letter with a request for prompt consideration of your request.

A letter of regularization should be written when an employee wants to become a full time member of a company. The letter should address the qualifying skills of the employee and the achievements made at the company.
