ID Please, Found Nhulunbuy NT

[Monica96]

Looking for an ID on these octopus species. Found a few specimens ranging from about 20cm - 80cm diameter. Found around Nhulunbuy NT.

Would also love to know whether this species is venomous or not.

Thanks

My guess is one of one of the macropus complex octopuses. Here are the two pages of the mostly candidates from Mark Norman's Cephalopods of the World.
