FEDERAL ELECTION: HOW WE GET THERE
* Malcolm Turnbull has the two triggers he wants to ask the governor-general to dissolve both houses of parliament for an election on July 2.
* The prime minister needs to make that call by May 11.
* Before then, parliament will sit for at least one week so that Treasurer Scott Morrison can deliver the budget and Opposition Leader Bill Shorten can give his reply speech.
* Once the governor-general issues writs for an election, the government is in caretaker mode. That means it can't make decisions without the acquiescence of the opposition.
