I use CommSec and it settles through my CDIA (Commonwealth Direct Investment Account)
I see that CommSec now offers two accounts in its own name, (even though it is owned by the Commonwealth Bank.) They are called CommSec Investment Account and CommSec Cash Account. It seems you trade with the first, and get 7.5% interest in the second, provided you can be bothered to shuttle the cash back and forth.
Do I have the story right? Should I move from my CDIA to these CommSec accountss? Any comments?
