Thorney International Pty Ltd itself was separately recorded as the third-largest registered holder, with a direct holding of 36,030,625 shares (5.78 percent), distinct from the larger 21.55 percent voting power reported in its substantial-holder notice, which aggregates associated Thorney entities.

Data availability

Country availability: Major shareholders only. Australian disclosure rules under Chapter 6C of the Corporations Act 2001 require public notification only once a holder reaches or moves across a 5 percent voting-power threshold, so the complete beneficial shareholder base of Austin Engineering Limited is not publicly available beyond the substantial-holder notices and the twenty-largest-holders register described above. No natural-person ultimate beneficial owner with a complete, dated ownership chain was identified in the sources reviewed.
