Hi Lynne! I know you've been looking for a group near you, so wanted to let you know we've just published the new 'member groups' section on the site which shows the location of all groups registered with BCNA. If you go to the search page and select Victoria (or type in your postcode), you'll be able to see what groups there are in your general area, and decide how far you're willing to travel.
Here's the link to the search page: http://www.bcna.org.au/membergroup/search.
Underneath the search boxes, you'll see the results display in a list, but if you click on the tab labelled 'map', you'll also be able to see them all pinned. Click on one of the pins and it will give you some more information about that group, and a link to the group page.
Hope that helps...
