If you're applying for a certificate of competency for the first time, you'll need to submit a completed Certificate of medical fitness for domestic seafarers.
This certificate of medical fitness must be completed by a qualified medical practitioner, such as a general practitioner, and includes both medical and eyesight tests.
You should download the Standards for the medical assessment of domestic seafarers [1] and provide this to your medical practitioner along with the medical form.
You can use a Certificate of medical fitness for international seafarers (AMSA 303) [2] if you have one.
If your certificate has a colour vision requirement and you do not meet the standard, your certificate will be restricted to operating or performing duties in daylight hours only.
Other application types include:
If you are applying for a low complexity certificate of competency, you must complete the declaration of medical fitness in the Certificate of competency application form 426 [3]. This lets us know that you are still medically fit, and that your eyesight meets the necessary standard, to work at sea.
The low complexity certificates are:
If you have any of the medical conditions listed in the form or you are applying to have a daylight hours restriction removed, you must also get a qualified medical practitioner to complete the Certificate of medical fitness for a near coastal certificate form [4]1850 [5].
If you are applying to have a daylight hours restriction removed and you do not meet the colour vision requirements of the eyesight test you must get the practitioner to provide a certificate or statement stating that you do not suffer any greater abnormality in colour vision than could be tested by the Ishihara Test.
If you're applying for a high complexity certificate of competency, you'll need to get a qualified medical practitioner to complete the Certificate of medical fitness for a near coastal certificate form [4]1850 [5].
The high complexity certificates are:
If you are applying to have a daylight hours restriction removed and you do not meet the colour vision requirements of the eyesight test you must get the practitioner to provide a certificate or statement stating that you do not suffer any greater abnormality in colour vision than could be tested by the Ishihara Test.
