pretty sure it's not illegal to sign up. It may be against livesport.tv terms and condition.
If a server in Australia is streaming it to a network in Australia it's not illegal. Virtually you'll be viewing it in Australia. Think of it like sitting on the border of one country while watching something across the border. Am sure I'll be challenged on that point, but that's how I see it (without knowing too much about how it works and loopholes etc.
I just know it's not illegal because I figure it's the same as signing up for netflix. Not illegal but against netflix T&Cs - but then they don't exactly enforce it as they like taking your money.
yeah that's a good theory but in reality however you get the content if you are watching it in NZ from a provider other than the rights holder your theoretically breaking the law - will anything actually happen? don't know - and that's the real question I guess. That's not just A-League that's anything that has rights owned in NZ - for example streaming premier league from a site other than PLP would be illegal.
You aren't breaking the law if you pay for it from an overseas source, probably just breaking that sites terms of service. It's a much greyer area if you just watch on one of the free streamming sites like firstrow or wiziwig. buying from an overseas site like Netflix can be compared to parallel importing. It's just like buying a movie or game or anything really off amazon in the states and then getting it shipped to you over here, that isn't illegal.
You can still get pinged by customs and have to pay tax/duties on imported goods
