Problem about non nude people is that they can make the nude feel uncomfortable.
In Austria a semi mixed bath recently closed their nudist area because it's surrounded by forest which was filled with perverts that made a lot of trash in the forest and would fap behind trees to nude people.
Same for any semi reachable other public nudist place I've ever been to, you have to expect perverts wandering around.
That's why I prefer places where non nude is not welcome, even thought I never have seen it enforced and nobody minds a clothed friend that doesn't feel it yet either.
Swanbourne north beach (the nudist part) is Federal land carved out from state title and exempt from local council rules - the inland area is SASR barracks and occasional training grounds .. you don't get a lot of perverts in the back dunes patrolled by squads with dispensation to black bag and interrogate anyone crossing an invisible line.
As for the nudist beach itself, it's mainly nudists who go there to be nude .. it's a tough search to find footage from that part of the beach as most people respect privacy.
The nudist beach is to the left, to the north, up the beach from the lifeguard building seen here in this drone footage:
it's a lot of empty space directly north of the clothed people with some dots of people in the far distance.
If you make it to the southern hemisphere you might like it .. people aren't prudish about nudity and mainly wear UV blocking clothes to avoid skin cancer .. people frequently strip and change in car parks when going out surfing | swimming | for a paddle.
How very German.
Here deregulated beaches (outside of council zoning) are clothing-optional :

which are often signposted as such near urban areas, with no signage or policing elsewhere:

... just don't disturb nesting turtles, okay?
