Newman points to mines over polls as he celebrates 2 years

QUEENSLAND Premier Campbell Newman has celebrated two years in office with the LNP faithful in Brisbane.

Mr Newman gave a speech at the LNP convention on Sunday; touting recent mining approvals as proof the government is improving the state's economy.

Despite a lull in the polls, an upbeat Mr Newman said the approval of Indian miner Adani's massive Carmichael mine in central west Queensland was key to turning around the state's fortunes.

He said the proposed mega-mine roads and a host of other developments were driving economic growth under his government.

Mr Newman also invoked a "crane indicator", saying there were 35 more cranes working on construction jobs in Brisbane now then when the LNP came to power in March 2012.

His speech followed a poll last week showing up to 40 of the LNP's 73 MPs could have been voted out if an election was held then.

Prime Minister Tony Abbott, who also spoke at the conference, also endorsed Mr Newman's leadership, saying key infrastructure projects could not happen if there was a state Labor government.
