Most of the east coast of Australia which includes Sydney and Brisbane, up along way on the way to Cairns are on alert. I have a friend in Eastern NZ, on the beach, and has emailed to let me know they have roughly 1.5 meter waves, that's about 5 feet.
In Australia, in effected areas up and down the east coast, most coastal/water events like surf carnivals, dragon boat races, triathalons, etc have been cancelled and people have been warned to stay away from the beach as localised shore flooding, although minor is expected, and strong ocean currents.
