A police community constable also attended the meeting of about 20 people and Mr Crosby said there were suggestions of residents getting photographic evidence to pass on to police the next time they saw these people engaged in sexual activity.
There was also a suggestion of taking down registration numbers of cars belonging to the offending people and putting notices on car windscreens asking them to be more discreet.
"We need to re-iterate that the majority of residents don't have a problem with nudists per se, as long as it's discreet. The problem areas are those two areas of parading themselves in front of people and the lewd behaviour that has been going on in the sand dunes. That's a very big difference," Mr Crosby said.
Resident Ben De Kleynen, who is the Neighbourhood Support representative for Sunbrae Grove, said the meeting helped establish future "action from us", Mr De Kleynen said.
