Yeah, thanks for your research, as I already said, I'll be declaring it if I continue, but if I don't do anymore I probably won't remember this fun week by June. June is 6 months away, I can barely remember what I did a fortnight ago.
For all the rules, I do wonder how many Uber drivers, Airtaskers, Upworkers & Airbnb hosts actually declare their income... I used an Airtasker once who asked me to cancel and pay them cash. Also I have my own business so I know 'how' to report income & expenses but the average person who's normally an employee, I dunno, it might all be too hard.
I use a tax advisor so I'll get advice about this and a whole host of things anyway, depending on what I remember, ha!
