This deal has been around for a fair while but is not a dupe so I thought some people might find this useful.
From what I can tell, joining community CPS is free and the day to day account is free also.
10% Discount only applies to AdamDirect and Naked DSL (not telstra resale dsl), most people are on AdamDirect.
May be applied to existing services provided residual contract period is less than 12 Months. So if you are with Adam already, go get a free transaction account with CPS then get the deal.
It applies to resold Telstra DSL too, cause I get it and I'm on an Adam ADSL1 8mbps plan.
Joining any Credit Union isn't quite free, you have to buy a share in the Credit Union… When I joined, 15 years ago, that was $2.
