It might be a bit different here in QLD, but at our local community kindy they offer a range of hours/days but the longest is 8am-4pm two days per week. We do 8:30-2:30 5 days per fortnight (I don't do paid work).

As a community kindy with no day care facilities, most mums don't work or work part time. A fair few days do either pick up or drop offs as well as grandparents. Being a community kindy, every is expected to help out on rosters including doing one day as the "helper" per term. It is great for the kids because it is like having an extra staff member every day.
