KLIP-LOK concealed-fix sheeting can be installed to a pitch as low as 1 degree in 0.48 mm base metal thickness, meeting AS/NZS 1562.1:2018. That is the usual answer for a flat rear extension where corrugated sheet would not comply.
Sheet metal roof and wall cladding in Australia is installed to AS/NZS 1562.1. It sets the minimum pitch, the fastening pattern and the side and end laps for each profile. Work that departs from it is what an insurer points at after a storm claim.
CUSTOM ORB corrugated profile is rated down to a minimum roof pitch of 5 degrees. Laid flatter than that, water sits in the pans instead of running off and the sheet holds moisture against the fasteners, no matter how well it is screwed down.

Roof repair in the Eastern Suburbs has its own rules: heritage areas, salt air and tight access all change how the job is done. Everything below links to the council or standard it comes from, so you can check it yourself.
Woollahra does not allow panels on the roof plane facing the primary street in heritage areas, limits projection to 500mm, and pushes slate roofs to a full application. It also asks for a 300mm setback from roof edges for future maintenance access.

The right roof depends on which precinct the house sits in, and a Section 10.7 certificate is the only definitive check.

The roof finish is often the most visible part of the building.

In the Eastern Suburbs it depends on the council and on whether the house sits in a heritage conservation area. Waverley Council lists 17 heritage conservation areas, including Bondi Beach, Charing Cross and Queens Park, where roof material and colour are assessed and most external work needs consent. Woollahra Council’s DCP does not permit concrete roof tiles in the Paddington conservation area, and Randwick treats repainting an already painted surface as maintenance that does not need consent.
