Yeah our dam is over 100% and just overflowing so the powers that be have relaxed our restrictions until the dam levels fall under the 100%. We had a "wet weekend" the Australia Day long weekend, where we could wash our cars, boats, houses etc and actually put the beach showers back on.
Re swimming in June - depends on how you like cold water. Not as cold as down south of course. I personally find it too cold then - wouldn't swim until Sept or Oct. We generally have about one really cold week in winter (lowest day time temperature is 15 degrees but can get quite cold at night)
