How much weight can a concrete slab support?

Hi there,

Can anyone tell me what the minimum and maximum
weight per square metre that a suspended concrete slab must be able to
support in accordance with NSW building codes?

I have an 8 yr old townhouse and would like to purchase an outdoor spa for the side courtyard, however I'm conscious that beneath the slab of the strata complex is the underground carpark and I want to make sure the slab can handle the weight.

I'm aware there are many factors that determine the overall strength of a slab, however I assume there must be a minimum weight bearing standard for any new residential development.

The dimensions of the spa are 2m x 2m with a total filled weight of approx 1500kg.

Thanks,
