7. Can I contact the case office regarding the progress of my application? Please use the Application Status page to view the progress of your application as we are unable to determine exact completion times. Please do not contact state branch offices as all skills assessment applications are processed out of the National Office in Sydney and state branch office staff members are not able to assist with enquiries. You can contact the National Office at assessment@acs.org.au or + 61 (0)2 9290 3422.
