It's the day before the election, and it's emerged that Australia secretly agreed to take in two accused murderers as part of its 2016 US refugee swap deal.

US news site Politico has revealed that two Rwandan men, accused of bludgeoning American tourists to death in Uganda in 1999, were resettled in Australia in November.

It's difficult to explain for a Government that's staked a large part of its reputation on a hardline refugee policy.

So could it lose the Coalition seats in the election? And what else don’t we know about the deal?
