Undara is out in the Outback or so it feels - getting there you drive along long sections of one track highway having to go onto the hard shoulder whenever you meet anything. Which included road trains leaving long trains of dust. But you can drive for miles and miles and see zilch. Well it's kilometres and kilometres as Oz is metric. And I did stop at the Windy Hill Wind farm by Ravenshoe (said Raven show) and the Millaa Millaa Lookout on the way.

What's at Undara? Collapsed lava tubes from a massive volcanic eruption - longest lava tubes on the planet I was told! Did a tour with a Scottish tour guide who kept making digs at the English.

The bird life at Undara was fantastic – right coloured parrots displaying in the trees so accessible and photograph available – loads of other birds also fluttering around. strange and impressive how nature crawls into every nook and cranny (tree roots hanging from the roof of the lava tube, white tiny arthropods in cave water). Undara is colourful (some times like an art gallery where you do Rorschach blot tests to see what you want to see) but the main difference to Carlsbad is that it’s formed by lava. A unique place but the science adds interest.
