I edited a montage on iMovie by cropping the footage of just the December 18th performance from the Racing to the Rainbow Show to show what Anthony's family in the Wiggles' 2007 concert video looks like as listed.

Lucia Field (2-Year-Old Daughter)
Miki Field (Wife)
Carla Field (6-Year-Old Niece)
Jacqueline Field (Sister-in-Law)
Maria Field (Baby Daughter)

We'll keep an eye out for the actual performance's unused footage where Anthony's wife Miki lifts their daughter Lucia up to give a rose to Dorothy and where Dorothy lifts Carla up to kiss her.
