Absolutely. We never used to say it in Oz. It came in a few years ago as a response to incursion after incursion after incursion.
It is an unfortunate trend that the rules are changing and continue to change to meet 'arse covering' requirements - to protect ourselves from the lowest common denominator (on both ends of the AGA).
It is a reflection of society's trend in the reduction of personal accountability, IMHO. Instead of having a rule (eg don't enter CTA unless you have a clearance) and then punishing the breakers of said rule (eg here's a fine or Yoink, there goes your licence) a redundant phrase is introduced as a tin plate exercise.
