What are the NCC 2022 insulation requirements for new detached homes in climate zone 5 across Australia?

For new detached homes in climate zone 5 under NCC 2022, the primary insulation requirement is achieving a minimum 7-star NatHERS rating, significantly enhancing thermal performance compared to prior standards. This typically necessitates increased R-values for roof, ceiling, wall, and floor insulation, while the accompanying whole-of-house energy budget further mandates optimised insulation strategies to reduce heating and cooling loads.
