MIHC, at the risk of creating severe thread drift, from your quotes, CAO 48 does not apply to a private operation. The DGs regs (and carrying guns for shooting drones) do apply because, as per your post, "the Reg says All Australian Aircraft, not just commercial ones".
Now go back and read the context of the quoted text. I was demonstrating where it says a CAO would not apply to a PVT operation.
Each CAO will define what type of op is covered in it's applicability or title, eg.
And 48 does apply if you also engage in AWK, CHTR or RPT.
