If you have a source with more detail, I'll stand corrected, but the one cited does not make the point you want it to.
I provided the except and link from the article “Qantas's wounded baggage handlers” above, 20% of the workers at one airport reported were injured.
Please this this report for the high injury report for the under floor loading of narrow body aircraft https://flightsafety.org/ao/ao_sept_oct98.pdf

“A major focus of this research project was also to measure the effect of ACE and Sliding Carpet, two commercially available retro-fit baggage systems, on the risk of back injuries to baggage handlers stacking baggage within Boeing B737 narrow-body aircraft.”
Under Australian law, as the manual loading is a known hazardous task, Qantas is obliged by law to take this into account. Eg.
Managing risks to health and safety
(1)A person conducting a business or undertaking must manage risks to health and safety relating to a musculoskeletal disorder associated with a hazardous manual task, under part 3.1.
WHS Act—section 19 (see section 9).
(2)In determining what control measures to implement under subsection (1), the person conducting the business or undertaking must have regard to all relevant matters that may contribute to a musculoskeletal disorder, including—
(a)postures, movements, forces and vibration relating to the hazardous manual task; and
(b)the duration and frequency of the hazardous manual task; and
(c)workplace environmental conditions that may affect the hazardous manual task or the worker performing it; and
(d)the design of the work area; and
(e)the layout of the workplace; and
(f)the systems of work used; and
(g)the nature, size, weight or number of persons, animals or things involved in carrying out the hazardous manual task.”

Similar legislation exists across the country, that is the workplace legislation Qantas has to abide by.
