Submission of the completed application form registers you and your immediate family members as a bonafide Northern Territory Fossicker for 12 months. Registration enables you to undertake fossicking activities on a declared Fossicking Area, although fossicking outside of such an area is allowed subject to obtaining relevant access permissions.
