overseas travel

hi Vicki,
it can be tricky to get travel insurance that covers pre-exisiting conditions. You may find our fact sheet helpful.

Also worth being aware that our goverment has reciprocal health care agreements with some countries (inclduing the UK) that means part of the cost of essential medical treament can be covered  for Australian residents visting these countries. Under these agreements some health services and subsidised medicines are provided to vistors if needed.
Have a look at the info on the link below. There is an enquiry line listed if you want more details.
