yay!!! I've been wondering when banks are finally going to catch up to the rest of the world and have sunday trading.

I think sunday trading is great. It's not like every worker has to work on a sunday and it gives students and so on a chance to work at a time that doesn't conflict with studies.
It also means that 2 working parents can schedule their rosters so as to minimise the amount of time children spend in childcare.

I've never been a 9-5 person and our business runs 24/7 so it's more convenient if other businesses do the same thing. DH spends more time with his children than other people we know who have 9 to 5 jobs so I think that family time is more about the commitment that parents make to create it than the hours their workplace operates. The only other dad we ever see at swimming and football lessons is the guy who works sundays and nights. Working those hours leaves him free to participate in his children's lives in ways that dads who work traditional hours can't.
I wish Australian banks had the kind of customer service that banks in some other countries have. Whenever I need to contact my bank in England I just pick up the phone and call. It doesn't matter what time of day or night it is over there, a real person always answers and is genuinely helpful. They don't even charge me bank fees.

ETA - in regards to people needing a cycle. I'm pretty comfortable without one and even supposing that I'm a freak and most people do need one then there's no rule that says it must be the same cycle. I once had wednesdays and thursdays off and TBH it was great. I could do all my banking, shopping etc on my days off and since I worked nights I could still go out late on the weekend nights and get up in time for work. It was like having 2 weekends every week.
