Research with mice suggests that you last longer with higher thyroxine doses, so definitely don't skip the pills!
Tell the Aus CAA in the first instance, and you will be advised to ground yourself until you are stabilised on a dosage (and are no longer tired!) - two blood tests that are stable on TSH and T3/T4 - or whatever you condition requires.
I don't think anyone knows truly why this develops, as the symptoms can be so mild in many cases (many old people are reckoned to be hypo and undiagnosed...) - it is an autoimmune-linked disease nonetheless...unless you have been playing with radioactivity.
Speak to your AME, as the docs and fellow sufferers on here can't answer to your whole condition based upon the text alone...and don't be tempted to fly without having stabilised and told the Aus CAA. They are - at least in the UK - extremely helpful in the medical department.
