"A sense of greater vulnerability is emerging among lower and middle income households," the report said.
A net 15 per cent of lower income respondents think their jobs will be less secure in a year's time, up from 3 per cent in the September quarter, while just 9 per cent expect to earn more, down from 31 per cent.
Richard Miller, managing director of McDermott Miller, said public sector employees were more pessimistic than their private sector peers, underpinned by the "realisation that the employment opportunities will be restricted in the future, anxiety over job security and lower expectations of earnings."
Earlier this week, online job website Seek said the average salary advertised on its site rose 5 per cent to $73,530 through the first 11 months of last year, led by sharp increases in the mining, resources and energy sector.
The national increase in salaries advertised on Seek outpaced the 3.2 per cent annual increase in average ordinary hourly wage to $26.53 by the end of September, according to government data. On a 40-hour working week, that equates to $55,182, or one-third below the average advertised salary on Seek.
