For those who inquired about C. luhuanus distribution, I just remembered an older paper by Ian Poiner and Catherine Catterall that focuses on human predation effects but includes data on population density, etc. in Papua New Guinea and Australia:

I. R. Poiner and C. P. Catterall. The Effects of Traditional Gathering on Populations of the Marine Gastropod Strombus luhuanus Linne 1758, in Southern Papua New Guinea. Oecologia 76: 191-199, 1988.
