Grab some sealant from a detailing store spray it on, let it sit, buff it off and rest easy
I only know of Carcareproducts here in sydney but I'm sure there's someone in Perth in the business. The products I'd go for would be either OptiSeal, Duragloss and Zaino (I think they're made by Duragloss). DMS Dan will be able to give you exact product names.
