Huge thanks to Dr Laura Graham! Everything they did is on github:

Prof Alasdair Rae was also big help and sent me their slides.

Thanks to Phil Chapman for sending in the question and taking the time to record themselves reading it for me.

Geoscience Australia were super helpful and answered all of my ridiculous questions.

Check out Steve Mould's Numberphile video on fractal coast lines.

Thanks to Bec Hill: comedian; podcast host; and the new voice of Geoscience Australia.

CORRECTIONS

- At 14:02 I accidentally say a 9 instead of a 7 (the area is 247719 not 249719). The on-screen numbers are correct. Phew.

- Let me know if you spot any other mistakes.
