Inheritance tax in Australia

Just putting out a hypothetically situation based on the fact that Australia has zero inheritance tax. If an elderly couple move to Australia for few years (five years ordinary resident) and buy a property. They can gift thier home to children settled in Australia before returning to Ireland. Does that make inheritance tax free ?

Why would they need to buy a home?

If it works, just give them the cash.

I think they would need to already have the rights to reside in Australia. A relation tried to move there to be with their only remaining close family relatives. But could not get the required visa, because they were of an age where they could become a burden on the state.
