The portable gps devices wouldnt be considered illegal as they are "secured in a commercially designed holder fixed to the vehicle" with the suction thingy.
Looking over these there aren't any real new rules, they have just modified existing rules or defined them more. Overtaking on Westgate has always been illegal, just so many people do it and are unaware of it.
My mum got booked about 8 years ago for moving her car into a different spot in the same block, so not a new rule as fair as I'm aware.
