Sorry for your loss. There are many nudists in the Sydney area and so finding a local nudist or nudists to go to the beach should not be impossible. Your best bet here is to post in the Australia section asking for others who go to the beaches near Sydney. Outside of that, just going to the beaches to meet others is good as the nudist beaches in Sydney are friendly places where it is possible to meet others. There are also clubs and organizations in the greater Sydney area. I wish you much success in finding someone locally to share nudism with.
