Spots for beginners in Australia and New Zealand in March

Hello! Fly to Australia and in mid-March. Arriving in Perth then we want to fly to the Northeast coast (possibly to Cairns) and continue to explore the east coast,Tasmania, and then New Zealand. In January in Bali, we first tried surfing. Surfed for 8 days. The most exciting for us were flat waves as tall as a man in the Canggu area. We want to combine the sightseeing with surfing. What surf spots (sharks free) at this time of year in Perth, east coast and New Zealand you could recommend? Thank you very much.
