The normal cashback rate isn't as good as Dosh, but if you signup before May 14th, you'll get $100 cashback:

For this next deal, not sure if it's targeted, but I got this via email:

I've just checked with SBS via both phone call and web chat and looks like these promotions will stack.

So you add your partner to your card, you get $50 cashback. Your partner then apply for her own card and get $100 cashback, then add you to her card and get another $50.
To add an additional card holder to your card, download the form here:

Then email it to:

UPDATE:
Just checked with SBS again, it's $50 PER additional cardholder you add. So you can add your parents and your partner and that'll be $150 cashback.
The form says it has to be a family member, but I've confirmed with SBS that it can be your girlfriend/boyfriend as well. There is no limit to how many cardholders you add.
I'm with SBS & got this email - I don't think its targetted.
General experience with the bank is very positive
