Greens negotiating on fuel excise change

The Greens may be about to do another deal with the Abbott government, this time over indexation of the fuel excise.

"We're talking to the government about that," Greens leader Richard Di Natale told ABC radio on Wednesday, a day after the minor party agreed to support government changes to the aged pension.

But any deal on the fuel excise, which needs parliamentary approval before the end of the year, will depend on more public transport options and addressing some regressive impacts, he said.
