Try $90 per exam sitting, plus $25 to $60 for a call sign recommendation and $55 for the license. That would be the minimum, but if you went foundation, standard, advanced you can multiply that by 3. We had the opportunity to move to class licensing and free licensed, but old people here lost their minds about that and pretty much voted on mass to keep things expensive. The costs really have nothing to do with it. Its the lack of promotion and visibility that is the issue. In the USA you go to any big electronics convention the ARRL is there, wacker movement convention ARRL is there. In Australia, the WIA has no presence in any of the traditional recruiting grounds for hams, thus, old people die and the number of licenses decline. We navel gaze here and in fight over the ashes, rather than look forward to a future and plan accordingly. We have more peak organisations than you can poke a stick at and all of them are not worth a monkeys butt, for all the good they do. More interested in fighting each other than being the custodians and promoters of the hobby. A pox on all of them I say.
