If it runs the way it did my first year, suit and all the gear will be provided. I don't know if they'll have a Santa workshop up here or not. You can talk to me to find out more on the basics, and ring them on (03) 9527 8644 to make further inquiries, if you're still interested. You will have to have a police check done.
I'm assuming they only want males for the job of Father Christmas, though there may be openings for Elves if you're a lady-person.
