Australia Jewelry Attractions

My husband and I are planning a trip to Australia in
mid-August/beginning of September. Does anyone know of things to
do/see/buy concerning contemporary/“ethnic” jewelry? The first week
of September will be in Sydney but the rest is still open so I can
plan around any possible events or venues. Conferences, courses,
workshops, galleries,… ? Feel free to contact me off-list. Also any
MUST-SEE suggestions are welcome.

Thank you,
Linda Savineau
