An early July election is not probable, but it is possible, Deputy Prime Minister Barnaby Joyce says.
"I think that is one of the big mistakes ... possibilities and probabilities are getting confused on this issue," he told reporters in Sydney on Friday as he responded to speculation about government plans for a double dissolution election.
Australians would be going to the polls some time between July and October, Mr Joyce said.
"We're talking about a four-month period in a term of government that goes for three years. I don't think this is quantum mechanics."
If that meant going to an election at the first opportunity in July, "that is not a probability, that is a possibility".
