From May to November, thousands of Humpback whales migrate along the coast, passing right by Sydney Harbour. If the backpacker budget allows, hop on a boat tour from Circular Quay or Darling Harbour, where you’ll have the chance to see these gentle giants breaching and tail-slapping in the wild.
For a cheaper, more laid-back experience, head to coastal spots like Bondi Beach or the cliffs of North Head, with a pair of binoculars where you can easily spot the whales from shore.
If you are looking for a boat tour provided, you can’t beat Whale Watching Sydney, they are highly praised for their knowledgeable guides, comfortable vessels, and high success rate in spotting whales.
