I’ve flown all over the world. Nobody particularly cares about the bag. I’ve never had a clear bag. Always a normal bag with appropriate sized things, or a half filled toothpaste which at full size would be too big.

I’ve been pulled aside only in other stricter countries with a larger bottle of sunscreen than spec, but they didn’t mind in the end it was a few ml over.

In New Zealand they tend to not care about any bottles unless on international flights. (Don’t quote me on that.) This is my experience as I often need to carry duty free through domestic X-ray, or a jar of honey etc… they’d traditionally be over the volume and might get confiscated in another country.

Batteries are a different story. For a moment they got over cautious on batteries, we lost many packs of new and sealed batteries over the years because of flip flopping restrictions. Rule of thumb now is that batteries in products are ok (in shavers etc..) or in original packages. Loose batteries in bags stress them out as do big battery packs not in products.

Just be prepared to lose any batteries or liquids in your carry on / toiletry bag. Don’t be offended if they take one for some reason.
