I've just booked my ticket to see hacking mega star Kevin Mitnick destroy something electronically. He's in Perth on the 11th of October at the Crown. There's also an awards ceremony the following day which is a separate paid event.
There are discounted tickets available today (Wednesday) at $57.68 not sure often these offers come round, but it seems a reasonable price. I have nothing whatsoever to do with the organisers of this event.
