There are several government organisations to help with finances. We all know about MoneySmart - which is getting better all the time. However, there are two other organisations - NICRI and the Financial Information Service (FIS).
The FIS is run by Centrelink, though you do not need to be a Centrelink recipient to take advantage of their service. They run a lot of seminars on different subjects, like how to budget and what levels of Aged Care are available, and they also have one on one consultations (they say that they do not give financial advice - but you can ask questions about your finances and they can come up with interesting ideas) over the phone or face to face. I have been to a number of their seminars (usually about 2 hours - mainly in the capital cities, but they do give some at regional centres). All of this is free. Unfortunately, the seminars have probably finished for the year, so the web site won't have much information about the seminars.
NICRI is the National Information Centre on Retirement Investments based in Canberra, and they also do phone consultations (again, they stress that they are not Financial Planners). I have met them at the FIS seminars (I don't know if this happens everywhere, but in Canberra they often speak for half the FIS seminar, from a slightly different perspective).
The FIS people are willing to come and speak to clubs etc. about whatever topic the club chooses, so I think a Mustashian meetup may be able to have them along. FIS is supposed to be independent of Centrelink, but they can advise Centrelink if they think someone is trying to defraud Centrelink.
Anyway, these services are set up to provide financial information relevant to a particular person, and are currently FREE. So they might be worth talking to. Both sets of people obviously spend all day every day discussing people's finances, so they do have experience.
