So what is the Posi-fit and how do I get one?

Your local Autobarn, Supercheap, etc.
If you go to the electrical section and find the Narva Accessory sockets, you will find a two pin socket that has a post type keyway.
Take your lead in with you and show the staff if you need to.
It'll be about $15-$20 roughly, and comes with a flat dress panel as well as the socket.
Narva have a range of panels from single to triple outlets with a selection of outlet types, as well as Volt & Amp. meters, to fit.

This is the plug.  Which you should already have on the end of the fridge lead.
If you don't have this end on your fridge lead, it probably won't work out.

This is the Socket, although this is a double outlet.  Comes as a surface mount pod or as a panel mount.
