Calls to increase payments for those on Newstart have ramped up in South Australia, as a South Australian social services group compares the cost of a $75-a-week increase to that of a submarine.

Currently, unemployed single Newstart recipients receive $273 a week, or just below $40 a day.

South Australian Council of Social Service are calling on SA premier Steven Marshall to lobby Malcolm Turnbull for increased newstart payments, as the momentum builds in SA for better living conditions for Newstart recipients.
