Outback Vampires

I happened across this movie by accident on late-night television. Its very low budget is obvious from the start, when you're trying to work out if this is a horror or a comedy. Things just get more confused when the main characters meet the family of vampires inhabiting the strange abandoned house - I'm still not sure whether the characters and events making up the rest of the movie are the work of a surreal genius or of somebody who just couldn't be bothered with logic. Either way, I've never seen a film quite like it. I don't know exactly what audience to recommend it to, although connoisseurs of bad films will no doubt have a field day with it.
