The AHA sent Steve Parr down to little old Adelaide to check out the ANHC (he is the Vice President), and as part of that they have extended a discount offer to Australian home brewers wishing to join the AHA.
Use activation code AUS15 in the activation code field at www.homebrewersassociation.org/digital to receive a discounted membership.
In addition to saving 15%, a digital AHA membership includes the benefits of a traditional AHA membership with a digital copy of Zymurgy delivered via email or the eZymurgy app, instead of a mailed printed copy.
