I also notice recently the security guys at MEL international have been weighing baggage , no tjust a few but most it seems the last few times i have been through, and of course my carry on weighted 12.5kg, but it was a bag inside a bag and 2 notebook computers and a so on, i could have split the bags to get both under 7kg but they let me though without any issues. (I am sure the QF gold lugguage tages help the situation when they do check)
