The reason that Australian commercial brews don't get chill haze is that they filter the guts out of every drop of them and have done so since the early 20th century. I would imagine that even Coopers does so before re-inoculating for the bottle condition.
However the use of finings such as Polyclar has long been used in non filtered beers such as UK real ales. I quote from my new book "brew your own British Real Ales"
Auxiliary finings are optional post fermentation finings that are used in conujnction with insinglass finings to produce brilliant clarity in cask conditiond beers, but they must not be added at the same time as isinglass. Auxiliary finings make particles in the beer negatively charged, however when the isinglass, which is positively charged, is added, all the particles are attracted to it, becoming heavy enough to drop of of suspension.
They don't mention PPVT as such but obviously it's the same category of finings and in the case of the Uk ales they aren't using it for chill haze as such. I know that Buttersd70, as an example, uses Polyclar in his ales for long term stability not chill haze.
