What is the name of a spider that has a green body and red legs?

There is a spider called a Northern Green Jumping Spider, or Clown Spider (mopsus mormon), with a light green body and red spotted legs. You would most likely find one during the day in Australia. They have excellent vision and it wouldn't be likely for one not to see you sneaking up on it. These spiders actually vary in color. Some have red spots, but some do not. I couldn't find any other spider that matched your description.
