They are scammers, all over the world, already hacked optus medibank etc, no conspiracy, 50k on a Russian dark website can buy you lots of Aussies data including passwords, tosser, wake up, it's real.
If it goes card only later how's the government going to guarantee that all stores won't be hacked, like optus and medibank, I'll use cash every time, I'm sick of being told card only, my money walks out with me.
IT's a natural occurring phenomenon, I don't think anyone can blame the airline, nobody wants to be strapped in on a long flight, it happens, if you are worried just keep your seatbelt on and buckled down tight.
