Poor hit hardest under a GST hike

THE poorest families in the country would face a 7% hit to their disposable income if the Turnbull Government lifts the GST to 15%.

Analysis of the proposal by the National Centre for Social and Economic Modelling showed the richest would suffer only a 3% cut to their disposable income.

The Australian Council of Social Services warned it was a "regressive" tax and would require a huge compensation package for low income earners.

ACOSS chief Dr Cassandra Goldie said it would be a "complicated churn".
