Since Australia is regularly a participant in the Eurovision Song Contest, I wondered, what if it was part of the EU. What would be needed to make it part of the EU and what would the implications of Australias membership be both on the EU and Australia but also on the world?
To make this happen, a colossal shift in policy would be needed. Australia was since WW2 pretty much always aligned with the US. Making it leave the US' sphere and become part of the European sphere would require the EU to be the more attractive option. The EU would need to be a viable military force to project power in the Asia-Pacfic region and guarantee Australian security.
An enourmous point of contention might be the EUs protectionist agricultural policies. With Australia in the Union, European farmers would not be able to compete with cheap Australian agricultural products which might lead to said farmers becoming workers in labor shortage sectors instead. Would Australia being part of the EU bind Britain to it or would a hypothetical Brexit make Australia leave too? Imo Australia leaving once in the EU is unlikely since the Union would be too lucrative for both sides.
