How often are child care settings checked?

[JHShaw]

I'm trying to find out how often preschool settings are checked by ACECQA?  I can see that all settings have to be assessed against the National Quality Standards now (a bit like our lovely OFSTED),  but the certificates do not give an expiry date.  Every other online search has come up with a dead end.

I'm not sure, I know they can request one if they provide 14 days notice.
