The Queensland government had suggest that level 6 water restrictions will soon be in place for South East Queensland. The draft for level 6 water restrictions seems to focus more on businesses than individuals, so there's no real surprises for home users. Here's what this will mean for domestic water use:

• penalties for water use above 200 litres per person in a household
• For such premises reticulated (town) water is not permitted to be used for the filling, partial filling, or topping up of a rainwater tank or rainwater storage facility

you can read more about stage 6 water restrictions on the Qld water commission website.
