International Security - Soon have to seperate at screening

"From 30 June 2018, people travelling internationally will notice some changes to the screening of carry-on items when departing Australia.

Passengers will be required to present all powders in their carry-on baggage separately for screening."

The TravelSECURE website now has the details that powders have to be removed from bags (no plastic bag needed). It's separated into two categories:

"Inorganic powders - 350gram limit per person (eg Salt, Salt scrub, Sand, Some talcum powders, Some powdered deodorant, Certain foot powders, Powdered detergent and cleaning products)"

"Organic powders - no limit but still need to be removed from bags (eg Powdered baby formula, Powdered food, Coffee, Protein powder, Flour, spices, sugar, Most cosmetics and Epsom salt)

I appreciate this is all in the name of safety but I can see this will cause confusion as to what people need to take out as it can already be confusing for those not traveling often. I've just copied and pasted the list above but I'm already confused .
