This table shows the average income of households in Australia, split by groups of 20% by income; as well as the highest and lowest 10% and 5% income groups.

2017-18: Somebody in the highest 20% group lives in a household with over twice the average weekly disposable income of the middle 20% ($4,166 per week compared with $1,884), and five times as much disposable income of a household in the lowest 20% ($753 per week). The average income of the middle 20% ($1,884a week) is two and half times that of the lowest 20% ($753). Income is heavily concentrated at the top: average income in the highest 5% (at $5,796) is more than one-and-a-half times the average of the highest 20%.

2015-16: This shows that somebody in the highest 20% group lived in a household with over twice the average weekly disposable income of the middle 20% ($3,978 per week compared with $1,779), and five times as much disposable income of a household in the lowest 20% ($735 per week). The average income of the middle 20% ($1,779 a week) was two and half times that of the lowest 20% ($735). Income is heavily concentrated at the top: average income in the highest 5% (at $6,063) was more than one-and-a-half times the average of the highest 20%, and the average of the top 1% (at $11,682) was almost three times that of the highest 20%. The average disposable income of the highest 1% ($11,682 per week) was more than 26 times that of the bottom 5% ($436). This means that the highest 1% received as much income after tax in a fortnight as the lowest 5% received in a year.
