Library Genesis has quite a few ISO standards.

And using Google, Bing and Yandex with the parameter "filetype:pdf" is also surprisingly effective.

I haven't tried searching for any Australian standards, but maybe that's a starting point?

It's worth asking your local library. My library card gives me read-only access to every ISO standard I've ever needed.

There's also the Estonian standards institute which offers the same standards for much much cheaper.

Are standards still a thing? My shrimp is radioactive and they are building vehicles too big for the roads, to mention only a few.

AS = Australian?

I know AS as = Aerospace, as in AS9100, AS9102, AS9145, AS13100, and more. The first at least is fairly easy to get a copy of via basic torrenting; current rev is D.

The "easiest" way to get a copy is to be in industry and use your company's resources to obtain a copy.

AS9100 is the "base" and it is just ISO9001 + some extra aerospace-specific additions.

evs.ee at least offers ISO standards at a not extortionate price:

The pdfs do have some DRM on them and they will come watermarked with the buyer details though. The former is easy to get around - I used foxit reader and a pdf 'printer' to make a copy that opens nicely in anything.
