Hi Mate, i was in a same situation and same occupation a while ago,
You will just need a signed E medical consent from the parents and you will just need a Letter from your GP stating that baby is good healthy and with usual development for a 3 months old baby.
you do't need physical examination.
This is what case officer has asked
MEDICALS : As your child is less than six months old and in Australia, an “on the papers” health assessment can be completed - that is, you do not need to physically take him to a Migration Medical Services Provider clinic in Australia for a medical examination. We will need to ask for an E-medical consent form for the child so that an “on papers” can be done, providing this is all supplied before the child is 6 months old
Before I can request an “on the papers” health assessment to be undertaken, I need you to provide me with the following additional documentation:
· REPORT /LETTER from your child’s treating general practitioner, paediatrician or obstetrician in Australia
It should state that they have examined the child and provide details of the child’s health and development including, but not limited to:
o general health,
o growth parameters (height, weight and head circumference),
o hearing,
o vision,
o and if relevant, chromosomal abnormalities, physical or intellectual impairment, or conditions that may result from maternal-foetal or maternal- neonatal transmission (for example, HIV infection), and
i hope this helps
