Have you heard of the website meetup.com? A FREE site, no fees as the website makes money from the group organisers. You just need to register with an account from a registered email address. Here are the groups I found in Melbourne relevant to dating.
- Amourlife Speed Dating Events Adelaide - Friends Down South 30s and 40s - Adelaide Social Singles - Southern Burbs 50+ Singles - Northern Adelaide 30s and 40s - Over 45s and loving it - 50 to 60 somethings Happy Hours & Good Times - No Kids No Worries: Childfree in Adelaide
redhotpie.com.au is an adult dating service for singles and swingers throughout the world. I don’t think there are many sites dedicated to this segment. They did have some negative media attention awhile ago about creating fake profiles around the time they starting charging fees to use the site.
