Migrants will forced to wait four years to access welfare benefits from July saving taxpayers $203 million.

However, the Turnbull Government's tough talk on new arrivals is occurring despite Australia continuing to accept new than 200,000 immigrants a year, which is almost triple the 20th century average of 70,000 per annum.

Last year, the government raised the waiting time for migrants to get social security from two years to three.

However, Treasurer Scott Morrison has announced that from July 2018, they will have to wait four years to get welfare, in a budget measure designed to save taxpayers $203 million over five years.

The budget papers highlighted this as a savings that would 'further support the sustainability of the welfare system'.

Scott Morrison has this year slammed former prime minister Tony Abbott's call to slash net annual immigration from 190,000 to 110,000.

He also reportedly argued against Home Affairs Minister Peter Dutton's call in cabinet to trim immigration to a still high level of 170,000 a year.

One Nation leader Pauline Hanson slammed the government for doing nothing to rein in Australia's high immigration rate, which has been above the 200,000 mark since 2012.

'Immigration does not mean we have a strong economy,' she told Sky News presenter Paul Murray on Tuesday night, adding Australia would be taking in almost one million people in just four years.

The Department of Immigration in September 2016 forecast Australia would have a net immigration pace of 225,700 by June 2018, rising to 231,700 in June 2019 and to 246,700 by mid-2020.
