Prime Minister Tony Abbott says some of the new minor parties in the Senate will be easier to deal with than others, when the upper house changeover takes place next year.
Mr Abbott was responding to questions about how he would deal with minor parties in the chamber, like businessman Clive Palmer's Palmer United Party (PUP).
"I will treat all members of parliament with courtesy and respect," he told reporters in Melbourne on Thursday.
"I dare say some of them will be easier to work with than others.
"But I'm certainly going to give every one of them the benefit of the doubt, and I'm going to give everyone of them the opportunity to work constructively with the new government."
Mr Abbott said Mr Palmer was a "significant figure" in a minor party and he wasn't going to run a commentary on minor parties.
"I'm going to try to make it a rule to be very sparing on comments on other political parties," he said.
When the Senate changes over on July 1, 2014, the coalition is likely to hold 33 seats to Labor's 26.
This means it will need at least six extra votes to pass legislation in the upper house.
The PUP will have at least one Senate seat, for Tasmania.
The final Senate result is still more than a week away.
