The $500 an hour superman wage in New South Wales is the highest in the country, according to an analysis of a range of wage scales by the Australian Institute of Company Directors.

The superman wages are the highest across the nation and come in at a rate of around 20 per cent higher than the median wage across Australia, according a report from the AICD.

A report from AICd.org.au, which is funded by the federal government, said the superman pay scale was particularly high in Western Australia and Queensland, and that the AISD found superman had the highest overall level of pay inequality.

According to the report, the superwoman wage in Queensland is $11,945, while in Western Australian it is $10,000.

“This shows that even within the richest states in Australia, the wage gap between the super and ordinary worker remains large and is still disproportionately high,” the report said.

It also found the super woman wage was the highest of all the wage scales across Australia.

Despite the highest wage inequality in Western states, it is the states where workers are paid the highest.

The states with the highest average wage inequality are the Northern Territory ($15,814), the Australian Capital Territory ($11,950), New South Welsh ($11:11), the Northern Rivers Territory ($10,907), the South Australian and Western Australian regions ($9,948), the Central Queensland ($9:20), the Sunshine Coast ($9), the NT ($8,979), the Southern Territory ($8:50), and the South West ($7,848).

The report found there was a significant gender pay gap in NSW.

Across the board, women in NSW earn an average of $9,716 less than men, the AICSD found.

But the AISC found that women’s wage inequality is concentrated in the Western Sydney, North Shore and South Coast regions.

In Western Sydney the superwomen wage is $15,880, compared to $14,834 for the average wage of the average male worker, and $13,931 for the median pay of the men in the same region.

While men earn the highest rate of wage inequality, the report found that in the Northern Territories, the gap is smaller, with men earning $11.9k less than women, while the average difference in wage is only $8.5k.

Women also earned the highest pay in WA, where the average female wage is around $13.8k, compared with $11k for the men, and the average gap is only 1.5pc.

Western Australia is one of only three states in which women are paid less than their male counterparts, and in other states women earn about $15k less per year than men.

Wage inequality in NSW is higher than in other parts of the country.

Among the states, the highest wages for women are in the Eastern Seaboard states, where they earn an estimated $11 and $10k less, respectively, than men in Western Sydney.

Another difference in wages across states is the size of the gap in the wage scale for women in Western Victoria and Queensland.

Men earn the average in Western and Northern Australia an average $11K less than the average woman, while women in Queensland earn $10K less.

Queensland has the highest inequality in terms of gender pay, but women in the Sunshine State earn $11 for every $1 for men.

In Western Australia, where women make $12k less each year than their counterparts, men make $16k less for every dollar they make than women in New Zealand.
