Link Market Services | Aussie Stock Forums

I just got some mail from a Telstra that I have shares in saying-

Your CHESS sponsor (Broker) has requested Link Market Service Limited to amend your Bank Account details

Now Ive just opened a CDIA account and Details in the letter indicate the Dividends will now be paid into this account

Firstly Do I have an option (doesn’t bother me But would have been nice to be asked)

Secondly how did Telstra find out (Privacy act???)

Thirdly Whats it got to do with Link Marketing Service I thought Telstra would have handles this them self??
