Try this toll-free number for Australia 1-800-083-293. I hope this helps. I think they can either process your request, or transfer your call to LDS Distribution Services in the USA, who can look after it. Either way the call will be free and you will only need to pay the equivalent of 6.75$US for the software.
I like PAF Companion's abilty to produce PDF versions of charts that I can post on my website or email to relatives who want the info but don't understand gedcoms.
