These frames fit all standard sized Australian number plates including standard sized personalised plates but DO NOT fit the Slimline plates that some cars in NSW, Qld and Vic have on the front. There is a discount table for bulk purchases at the bottom of the page. The reduced prices for larger quantities are applied automatically but the delivery costs may be much more that the actual cost ends up being. We will refund excess freight costs automatically if this occurs. You could also email us with the quantity you require and we will get a quote for you.
