Video: The video opens on the Aus Post logo.

Audio: Audio throughout is a backing track playing a fairly happy tune.

Video: We see an Australia Post postie on his bike, wrapped in a suit of bubble wrap. x3 Letters representing each of the three speeds fly out of the logo. The logo turns into a calendar with the 4 Jan date. This then changes into three separate squares with each letter (Express, Priority and Regular).

Audio: Australia Post is making some changes, giving you more choice over the speed at which you send letters. From 4 January 2016, there will be three speeds for sending letters within Australia - Express, Priority and Regular. We hear a 'shoopy' sound as the letters fly out of the logo.

Each speed has a sound (beep/tone) as a trigger for the audience. When the three speeds first come into frame, we hear the beeps in ascending order.

Video: A purple square appears on screen with the word 'Express'

Audio: Express

Video: The Express letter then appears with the price $5.75. A hand appears holding the letter with a red tracking beacon. The letter is then placed in a yellow street posting box.
