My opinion only....I think labor will vote in unison on the new super changes BUT they will insist that the $500,000 once only total payment will start from the 1st July 2016 otherwise it prob wont get through the senate....I expect a trade off would be the $1.6 million threshold as labor want to reduce that to say $1.5 million....and a tax on withdrawal amounts over $80,000..
I can see the Libs cross benchers having a greater say but the labor contingent will out vote them if it goes that way .
as I said , only my opinion.....
