It was every whale watchers' dream: the rare sight of a humpback in full breech off the coast of Kurnell on Sunday.
Leader reader and Woronora resident, Patrick Senior, captured this rare image, while out on a boat with his children Keylani, 3 and Jordan, 2.
''We were out in the boat in the hope of at least a glimpse of these beautiful mammals,'' Mr Senior said.
At Wattamolla and Garie beaches, whale watchers could have been mistaken for thinking it was Mother's Day on Sunday.
There were plenty of humpback whales about, including a mum and a calf.
Leader web reader, Debbie Andrew, captured the below picture of pair of adult whales just moments after the calf sighting.
There have been about 900 whale sightings off Cape Solander in Botany Bay National Park since May.
