Finding common ground with Clive Palmer ahead of the new-look Senate would be pointless while he keeps shifting policy stance, the Australian Greens say.

Willing but pointless.

That’s the Australian Greens’ take on discussions with Clive Palmer, whose senators will control valuable votes in the new-look upper house from July.

“I’m ready to take the call from Clive. I’m ready to meet Clive at any time to talk about issues,” Greens leader Christine Milne said on Thursday.

But such a meeting would be fruitless.

“Clive has a different view of issues every time he speaks,” Senator Milne told reporters, adding that she hasn’t tried to contact the colourful Queensland MP ahead of the Senate changeover.

“Until the Palmer United Party (PUP) has a policy position that’s consistent on anything there doesn’t seem to be a lot of point.”

The senate makeover will bring in three PUP senators and the party has already built an alliance with Motoring Enthusiasts Party representative Ricky Muir.

Speculation is rife about preference deals, which would have the power to block government legislation.

Senator Milne said the Greens haven’t had discussions with any crossbenchers.

“We will work with them on the issues as they come forward.”

But she maintained that the Greens remain determined to vote down the Abbott government’s proposed Medicare co-payments, university deregulation and “attack on unemployed”.
