Further updates: After writing an unflattering review on productreview.com.au, it gave me the option to send the review to a Company Rep for mediation before publishing. I had my claim assessed and approved the following day. After the money hit my account I still published my review. I wonder how many reviews don't get published?
I forgot that I also had insurance through my NAB card so I claimed the remainder I was out pocket through that insurance and their underwriter, Allianz, who also paid out. No issues.
My NAB insurance is actually more generous than the Insure and Go policy. I don't see any glaring gotchas in the NAB PDS so going to rely on this for an upcoming trip to Turkey and Greece and also have a backup insurance policy with Covermore, provided 'free' through the Commbank Ultimate credit card.
It appears the Commbank Covermore policy is similar to the paid Covermore comprehensive policy and only requires activation through internet banking with no spend requirement on the card (return ticket, etc). If you are going to take out a paid comprehensive Covermore policy directly with Covermore, a more affordable alternative may be getting a Commbank Ultimate credit card instead (no annual fee when you spend a certain amount on the card each month and no foreign transaction fees) and activating the insurance before you leave. I only discovered this card yesterday when looking for no foreign transaction fee credit cards and haven't read the PDS yet so take this information with care.
Cheers
