The pitch by Prime Minister Peter O'Neill came while addressing attendees at the PNG Mining and Petroleum conference in Port Moresby yesterday.

"We need to work together to bring forward some of the key projects, such as Elk Antelope, Stanley gas, P'nyang gas, Wafi-Golpu and Frieda River," he said.

"But of course, we will not sit back and wait for the price of oil and gas to go up [and] we will not sit back and wait for commodity prices to improve.

"[We] are very proactive to ensure the right climate for ongoing investment in our economy - particularly in our resources sector, is maintained."

O'Neill also reassured the business community that there will be no "intentional surprises" when the government reviews the recommendations offered by the recent report from the Tax Review Committee, saying community and industry consultation will commence next year.

"This engagement with the resources sector, business and with investors is vital," he said.

"This government will not adopt revenue measures that would only serve to undermine the longer-term competitiveness of our economy."

Value-adding PNG's LNG reserves was also touched on during the speech, with O'Neill saying the government will look to broadening the oil and gas sector by focusing on downstream processing.

"The government will encourage and offer incentives to gas projects that include downstream processing and the development of affordable energy supplies to our business community and to our citizens," he said.

"To achieve these ends, [our] own corporations will be required to work closely with the private sector in maximising our opportunities."
