A new study has revealed Australian women are retiring with half the superannuation that men do, largely based on parenthood.
Australia has an ageing population, and research suggests that, for half of the workers, a big bump awaits on the road to retirement.
Warwick Smith is co-author of a new report into superannuation outcomes for women, entitled the Not So Super for Women report.
He says the gap between women's and men's superannuation is big.
The Australian Services Union and the Australian research centre Per Capita have drafted recommendations to the government and private sector to close the gender pay gap.
