Hi @Lindsay16,
A warm welcome to the Bunnings workshop community, it is fantastic to have you with us.
The edging is melamine. You can replace it with this Moroday White Iron-on Melamine Edge. It has a heat-activated adhesive so it can be cut to length, sat in position, then ironed to activate the adhesive. Once in place, trim any excess with a utility knife.
Make sure you wear some gloves and long protective clothing to prevent lacerations when working with knives.
Let me know if you have any further questions.
Jacob
