If you are in Melbourne, I highly recommend a visit to the Salvador Dali, Liquid Desire exhibition at the NGV.
Pre marriage & kids, Roger & I were lucky enough to spend a few days in Cadaqués, where Dali's family had a summer home. We tried to make it to the museum in Figueres, but the closest we got was a drive by. I hope we get the opportunity to go back with the kids one day.
If you do go, I would recommend purchasing tickets online beforehand, as the queue was long, although it did give us some time to brush us on our Surrealist drawing skills.
