In the U.S., nisin is used to inhibit outgrowth of Clostridium botulinum spores (the cause of botulism) and toxin formation in pasteurized process cheese spreads with fruits, vegetables or meats at levels not exceeding good manufacturing practice. Current good manufacturing practice in this case is the quantity of the ingredient that delivers a maximum of 250 p.p.m. of nisin in the finished product. Nisaplin-brand nisin is also approved for liquid egg products, dressings, and sauces. In other countries it is also used in fresh and recombined milk, fermented beverages like beer, canned foods, frozen desserts, and high moisture/reduced fat foods.
Nisin is considered effective at controlling a wide range of gram-positive organisms including: Listeria, enterococcus, Bacillus sporothermodurans, and clostridium. Used alone, it is not effective on gram-negative bacteria (like E coli ), yeasts, and molds.

One handy litte hint. Use the google site: function. This restricts the search to only sites containing whatever you specify.
eg, entering the search string "preservative site:.au" would only return australian hosted sites, with .au in the address.
This can be restricted even more, down to one site.
eg "GMK inline filter site:www.aussiehomebrewer.com" only returns a few results from this forum about the GMK filters.
You can find more info here.
here endeth the lesson

Thats what i thought too,hence my research to get to the bottom of this possible myth.
I typed 'australian beer preservatives' into google and got a myriad of sites related to micros and coopers.
All of them make a point of saying their products are free from preservatives.
This sort of implies that other major brewers are using preservatives.or its just marketing bullshit ie ur product is preservative free is just used to make you suspicious of other's products, and trust only theirs.Which makes it a baseless statement.
