Add tub and ensure compliant plumbing

Photo shows washing machine area… The space is about appears to be able to fit a 35cm tub alongside a 56cm wide 6.5L washing machine with a 2cm gap in between. Not sure if this would require any additional plumbing/drainage provision which I believe triggers consent requirement?.... Builders report said plumbing appears good. However I am also wondering what/if any needs to be done to make this more legit/compliant plumbing. Suggestions so far from internet are a goose neck on the waste pipe to stop vermin and sewer fumes and a couple of pipe saddles/ slips to fix up stand pipe to wall and wall to stop it moving around and when machine pumps out.
