Hey Tasneem, I've been reading about fair use in photography, and I may have misled you. I wonder if using those news images you've nabbed might've been OK.
Apparently, you can 'quote' other people's images for comment or critique, as long as they're fully credited. This must be how the newspapers get away with stealing people's social media pics.
I don't know how the rules differ in Australia, but this is a guide in the UK to fair use. Apologies. https://subjectguides.york.ac.uk/copyright/images
I've corrected my latest post about the competition too, because it seems it falls into fair use. Perhaps I should shut up about copyright and let people take their own risks.
