'Eurovision' is the name of the broadcasting network of the EBU.1. To your best knowledge, what could be the core meaning of or the idea behind the word Eurovison, as part of »Eurovision Song Contest«?
2. Given that meaning or idea – could a country like Israel or Australia really be a perfect representative of it?
EBU members can receive it. It doesn't matter where they are in the world. The song contest is named after the network. The name has nothing to do with the European continent other than the EBU orginated there. If there was a 'CBS Song Contest' (God forbid) there'd be no reason to reject entries from countries outside of America. It's the same thing.
Not confined only to Europe, the EBU is the "largest community of public service media organizations throughout the world". It currently encompasses 113 television broadcasting organizations located in 56 countries of Europe, North Africa, and the Middle East, for a total of 68 associated broadcasting organizations in Europe, Africa, America, Asia, and Oceania
