If you have a silver, gold or platinum Visa or Master Card and you pay more than 50% of travel on them you have automatic travel insurance. Just find out and call the insurance company on the card and ask them about it. So many people have credit cards and are not aware of the travel insurance. They also cover you for that EXCESS Car hire companies talk you into. If you are in private health insurance they have travel cover also. But I think most won't cover you for anything that happens to do with your BC - but if anything happens that is related to your BC you'd come home I would think anyway rather than be treated in those countries. Given your time frame since treatment Id say the BC isn't an issue. RACQ, Covermore but make sure you do it with a reputable company. But check your credit cards first. :)
