If you have a drone, get it out! Because the shots at Lake MacDonnel are insane from above, splitting the pink and blue water perfectly. I'd recommend getting here in the morning or afternoon of a clear day, to avoid the sun glare in your photos.
Located on western Eyre Peninsula near the Nullarbor Plain, Lake MacDonnel is a salt lake that used to be a salt mine but is now the largest gypsum mine in Australia! It's a pretty big deal in the mining world down under!
