Form 888 is an Australian Immigration form that serves the purpose of providing character references for a visa applicant. This form is used by individuals who are applying for certain visas, such as Partner visas, Skilled Migration visas, or Business visas, to demonstrate their good character and suitability for visa approval. The form is usually completed by individuals who have known the visa applicant for a significant period of time and can vouch for their character, personal qualities, living arrangements, and any other relevant information that may support the visa application. The purpose of Form 888 is to provide additional evidence of an applicant's character and to support their claims made in the visa application.
