Replicate Address Input Fields using Google Places API

Refer attached and the cart at [login to view URL] We wish to replicate the delivery address area. 1. The form asks for a delivery address 2. Upon starting to enter an address, show matches from Google Places API 3a. If an address is selected, the first address input field is to become the address 1 field with address 1 information (i.e. street number, street name, street type / unit number, street number, street name, street type), and Suburb, Country, Postcode would be filled out. 3b. If "can't find your address?" is selected, the first address field stays as is, and Suburb, Country, and Postcode are shown (and are blank) 4. Ensure only Australia is available in 'Country', and that the Australian states are only available in 'State'. 5. Return a message if 'po box' or 'parcel' are entered in the address field (not case sensitive) and disallow the form from being submitted. Thanks!
