It's only illegal if your total salary would work out to less than minimum wage. Working 80 hour weeks year round at WA's 2020 minimum wage works out to $70k a year if you include time and a half after 40hrs/week.
Your job isn’t to do X hours of work your job is to meet a goal, objective or target. You don’t get to stop when the clock hits a certain hour in this industry.
Absolutely does. Everyone just signs to opt out of the 40 hour (something like that) working week directive and contracts are clear that there is no such thing as overtime.
