ok I guess this is something I should have got many years ago but I've never really ever been asked before except I had to get one for using the local online business register here just recently but I couldn't wait for that to arrive so ended up going in and taking the forms in myself. They sent me one out recently in the post but I haven't even opened the envelope yet.

Now I notice LS have an option to pay by direct deposit into my Australian Bank account which is great news instead of making trips to the bank etc.
So how and what Digital Signature do I need in this case and where to get it from, can I use the one the business register gave me?
