do it online if you're registered nic! all you have to do is find the bit that allows you to notify that you're not lodging a tax return - it should all update tomorrow. the phones will be ridiculously busy (even worse than normal) for at least the next month with those calls and people asking "when do i get my six hundred dollars"

the system will then wait until your DH's income tax info comes through - unfortunately, the ATO don't feed the info through in order received - i found last year some of the earliest lodgers were the people that had to wait longer for info to come through. if it comes through before July 16, it will process on that date and be in your bank two working days later - otherwise it will be two working days after the information is received from ATO

you can put in your non-lodger details anytime between now and july 16 and you'll get the same result time wise
