Water tanks

A rainwater tank doesn't need DA approval if:

it can contain up to 20kL
it isn't higher than 3m above datum ground level, and
the whole tank is buried under the datum ground level. This applies if any part of the tank is between a front boundary and a building line for the block.

Water tanks are class 10 structures. Extra criteria apply if you are building 2 exempt class 10 structures within 1.5m of a side or rear block boundary.
