Key difference
What is different in NSW?
Current and legacy pathways coexist. Contracts made before 21 October 2019 may remain under older reference-date rules, so the contract date matters. A claim must identify the work or related goods and services, state the amount claimed and say that it is made under the Act. Residential matters require Home Building Act checks. A head contractor claiming from a principal may also need the approved supporting statement. Service is its own step: an email address is suitable only where it was specified for service of that kind.
