I recognise this is an older thread however I thought my experience would be useful. Just getting back to travelling after a couple of medical issues with coronary artery and "waterworks". Refused by QBE for both pre-existing conditions and waited for a few months and applied to Allclear. They covered me for the pre-existing conditions but the premium for my wife and I was around AUD$2500 for a 3 week cruise next year. The application on-line was easy and quick with no further medical reports required, and approved imediately. In my view it is worth the high cost to be covered and I agree with previous comments you need to disclose everything and read the PDS. Even a change of medication dosage not disclosed, would allow the insurer to avoid a claim. After the overseas trip was insured we booked an Australian land tour and got insurance with Allclear again. Even though we are covered by Medicare in Oz I dislosed my pre-existing conditions again; if we had to cancel after paying the full cost because of one of those conditions the cancellation cover would not apply. I have an insurance background many years ago and in all honesty my opinion is that any travel insurer could avoid any claim using the detailed wording of the PDS! I believe Allclear has the same insurer as Insure and Go that is Mitsui.
