Australia will respond to international pressure and do more on climate change because it will not want to be seen as the "back marker", British Prime Minister David Cameron says.

During an appearance before a British parliamentary committee meeting held early Wednesday morning Australian time, Mr Cameron was asked by an MP whether there was hope Australia would do more because "the new Australian government is in denial" on the issue.

Mr Cameron did not disagree and told the hearing there was hope Australia would step up its efforts.

"They don't want to be the back marker, nor should they," he said. It's a great country, it's clearly affected by climate change and I believe they will do more."
