For medicinal purposes only

So I've read (no idea where) that if you take PBS medication, you aren't allowed to take it out of the country without a doctor's certificate (seriously wtf - if the box has my name on it which means its a prescription - why the hell am I getting a certificate to say I'm allowed to take it?!). 

I take a prescribed tablet daily, so I'm going to need to organise a doc visit before I go. What a PITA! Ah well.
