Video has emerged of an enormous 'tsunami cloud' approaching Sydney, Australia.
The staggering footage shows what is usually known as a shelf cloud rolling in at Bondi Beach in the east coast city.
Many took to social media to post their view of the storm.
Nick Moir, a photographer for the Sydney Morning Herald told Sky News that shelf clouds aren't necessarily rare, however "to get them so big and coming right up the coast of Sydney is not that common - you get a couple a year".
