Following the receipt of an ITA34 indicating the refundable amount, are there further steps needed?

Following the submission of my tax return I received an ITA34 (on the 25th October) stating that a certain amount was refundable to me. I've yet to receive this amount. Is this the usual waiting period? Is there something else I need to do?

Were you asked to submit supporting documents?

I don't think so.

According to the assessment you still have to submit the ITR12 from 2012, that is what is holding up payment of your refund.
