MINES Minister Anthony Lynham has addressed rumours he is not contesting the October state election.

During a press conference in Mackay today, the Stafford MP shot down the suggestion, telling the media "I've nominated".

"I got elected in July 2014; before the 2015 election they were the same rumours," Dr Lynham said.

"Every year there's rumours that I will not be contesting … I think the LNP want me out for some reason.

"I think it's because I deliver on lower power prices every single year."

When asked again what his decision was, he said: "My bid is in with the ALP, I've nominated, I'm ready to go."
