About the blood tests. Just go to your nearest walk in medical centre and ask the medico there to refer you for blood tests as specified in the DAME hand book because you don't feel too good. Medicare covers it then. That's the truth in my case, when I think about paying for them I definitely feel unwell.
Don't forget to have the blood taker add your name to the referral requesting a copy to your address so you can take it to your DAME. Blood tests must be done within 90 days of due date and it behooves us all to do them as early as possible, just in case of an abnormality which we now have a couple of months to fix.
