I find it somewhat curious that with this level of detail, that neither of the
words "inspected" or "tested", appear anywhere in the report.

Surely an organization with QANTAS much vaunted "safety culture" would have a
record of when and where these bottles, some of them near 18 years old - and
some older - were tested in accordance with CAR - wouldn't they?

And if so why not include it in the report.

Surely these dates are way more relevant than the date the bottle was fitted to
the aircraft??

After all, I can't get my LP BBQ bottle refilled without evidence of inspection.
