Insurance for Canadian in Australia on Working Holiday? (417)

Hey all! I'm posting this for a friend. She's a Canadian from Québec going to Australia on a working holiday visa (417). She's a little overwhelmed trying to figure out what insurance she needs.

Does anyone know what insurance she'll need to get for her stay? Not sure if there is a different kind of insurance or different companies for Canadians as opposed to Brits, Americans, etc.

Can you recommend any companies to go through?

Thank you so much!
