Poor kids can kick around a tin can or tennis ball, that is what is meant.
In regards to junior participation, the regular fees are normal, same as I experience with other kids sport, for insurance etc. The part I don't like about junior soccer is they continually tout for people to join the academy sides, which costs much more $$$ and you need to drive to Timbuktu all weekend for the matches, and as far as I can tell you don't get selected for rep sides if you aren't in the academies.
That academy part is more about the conversation of why Football Australia cannot convert very high junior participation into better quality international footballers, despite Australia being otherwise highly competitive in other international sports that have similarly significant funding and participation.
I tell all the soccer parents - if you play League and you are any good, you don't need to pay for an academy, the clubs will 100% find and fund you.
