In Australia, the legal reference for standards of measurement is defined
by the National Measurement Act:

https://www.legislation.gov.au/Details/C2016C00085

This also defines the legal source of time of day UTC(AUS), the Australian
realisation of UTC. State legislation then defines local time as an offset
with respect to UTC(AUS)

I only know of three industry-related "requirements". In the financial
markets, there is a requirement (via "Market Integrity Rules", overseen by
a government regulatory body) for synchronisation to UTC(AUS) to 20 ms. The
others, in transport and telecomms, are more like "codes of practice".

Cheers
