There are two big sets of livability rankings for international cities - the Mercer Quality of Living Survey and the Economist Intelligence Unit's (EIU) Liveability Ranking.

The two rating systems are designed to help employers determine pay scales for employees in international locations.

Key areas they cover are: Stability, Healthcare, Culture & Environment, Education and Infrastructure.

Australian cities perform well on both rankings but more so using the EIU index, which excludes accommodation costs.
