A BritVic is an Expat living in, or planning to move to, the state of Victoria in Australia. "Expat from whence?", you may ask. Great Britain, mostly, which is where most immigrants to Australia in the last 30,000 years came from. These ones have their own category: Category:BritVics.
One wiki-famous former BritVic is User:Angela, now known on Facebook as Angela Beesley Starling.
