Seems I was on the right track but it simpler than I thought. Not a word of the trade deal needs to be changed just our parliament to enact the legislation that would enshrine the rules regarding local jobs.

Craig Thomson interview with Tony Jones

" CRAIG EMERSON: Well you asked me about the ad and the ad actually is right in that there is no obligation to do labour market testing. It is left to the Department of Immigration. And what I'm suggesting is this: don't leave it in the hands of the Department of Immigration, which itself has said that under exceptional circumstances, whatever they may be, it would not apply labour market testing. Let's have this in the hands of the Parliament, the people's elected body, and have the Parliament pass a piece of legislation which says that labour market testing in all future trade agreements, including the China free trade agreement, is mandatory. That does not require changing one syllable of the China-Australia Free Trade Agreement - not one syllable.

How come Labor, under Rudd and Gillard never managed to get this Agreement in place.

 They had enough darn time to do so...if they had spent more time on this and not stabbing each other in the back the Agreement would already be there.

Labor says the wording of the China deal would not need to be reworked or renegotiated because the relevant provisions dealing with so-called "labour-market testing", could be addressed in the legislation in the Australian Parliament.

"We want to amend the enabling legislation around the trade agreement," Mr Shorten said on the campaign trail in Perth with candidate Matt Keogh.

"Let's face it, just because Tony Abbott gives Australians a proposition and asks Australians to sign a blank cheque, who in their right mind would simply agree with Mr Abbott when he says, just trust me," Mr Shorten said.

Asked for details of Labor's intentions, Mr Shorten said: "Mr Abbott hasn't even put the legislation to the Parliament ... why is it that above $150 million you're not going to require that a company tests to see if there's Australians who can do the job?"
