Hi @RRM300 and welcome to the forums.
Looking at the parts diagram they list as a 15W speaker and they also have a mounting screw which is also listed on the left of the pic below (item above the speaker entry). The speaker part number is highlighted in the list. The web site has no price though so you'd need to enquire with the dealer spare parts counter on that and the screws.
You might find a set of these at your local auto wreckers/salvage yard at a much cheaper price and with the screws included. Also check the web for the parts in Australia and they can be shipped by any wrecker.
You would need to do a speaker check once installed to ensure they are seen by the audio system. Speaker check is accessed from the hidden service menu on the main screen of the Smart Display.
