1978 Sterling Silver cricket bat pendant promoting Kerry Packer’s World Series Cricket

6 months ago on this feed u/MizzBeaten asked if anyone knew the significance of a 1978 Sterling Silver Cricket Bat pendant. I've been through the archived thread of that post and did not see a knowing response so I'm posting here with what I know.
I also purchased one of these pendants back in 1978 and I still have it 47 years later. Back then I understood it was promotional merchandise to promote Kerry Packer's push to establish World Series Cricket which ran between 1977-1979. I suspect it was produced by Meja International Pty Ltd (because MEJA it is stamped on my pendant).

Dennis Lillee certainly had a role of some sort, as he is seen wearing the same (or at least something similar from the promotional campaign) in https://au.pinterest.com/pin/188517934381825202/.

My pendant has STG.SIL, ©1978, MEJA and a symbol like a capital A, which is also seen on MizzBeaten's pendant. See her post at: https://www.reddit.com/r/Cricket/comments/1g1vvtq/does_anyone_know_what_this_is/

That's all I can offer. I note our two pendants are different in some respects with slightly different molding and inscriptions, but both seem related to the WSC promotions occuring at that time.
