Top 10 spectacular phenomena to experience in Australia
From the bizarre and surreal to the stunningly beautiful, here are 10 amazing natural phenomena picked from around Australia.
1. Horizontal Falls
Talbot Bay, Western Australia
The Kimberley marine 'waterfalls' are caused by huge tidal movements pushing through water through two narrow cliff passages – the first and most seaward about 20m wide, the second about 10m wide.
2. Red crab migration
Travel to Christmas Island during October and November to see the spectacular migration of red crabs from the forest to the sea.

3. Aurora Australis
Timing is everything if you want to catch a glimpse of the southern lights, best seen from southern Tasmania (or Antarctica).

These unusual long, rolling cloud formations occur in northern Australia during the spring and summer months.

5. Coral spawning
Great Barrier Reef, Queensland
Witness the annual mass coral spawning event that takes place in the waters of the Great Barrier Reef at night during late spring and early summer.
A scuba diver is perfectly positioned to witness a spawning event. The eggs and sperm will rise to the surface where they will begin breaking up. The sperm will seek eggs of the same species but from different colonies. (Image: Kevin Deacon
6. Wolfe Creek Crater
Tanami Road, Western Australia
The 880m-wide Wolfe Creek Crater was created by a meteorite impact about 300,000 years ago.
The meteorite that caused Wolfe Creek crater would have weighed more than 50,000 tonnes and is thought to have been travelling at 15km/second. (Image: Dick and Pip Smith)
Hamelin Pool, Western Australia
See what the Earth looked like 3.5 billion years ago, with these 'living fossils' - some of the oldest life forms.

8. Pink Lakes
If you've never seen a bubble-gum pink lake before, head to Lake Hillier on Middle Island off the coast of Esperance in Western Australia.

8. Filling of Kati Thanda/Lake Eyre
Frogs that have buried themselves and hibernated underground for years, insects, fish and millions of birds bring the inland alive whenever Lake Eyre fills.

9. Wildflowers of WA
South-western Western Australia
Known as one of the botanical hotspots of the world, south-western WA has some 10,000 flowering plant species, 75 per cent of which are endemic. Most flower from July to November.
