A Labor government would triple the fees for skilled migrants visas to work in Australia, establish a new visa for academics, set up a new training fund and establish a new independent body to test whether jobs can be filled by Australians instead of overseas residents.

And in an escalation of tit-for-tat "Australians first" migration policies, Opposition Leader Bill Shorten will accuse the Turnbull government of announcing "little more than a con job" when it announced the abolition of the 457 visa program last month.

The suite of prospective policy changes also include a promise that Labor in government will not sign another free trade agreement that allows local labour market testing to be waived, as the South Korean, Japanese and Chinese deals do.

They will be unveiled by Mr Shorten in a pre-budget address to the McKell Institute in Sydney on Wednesday.
