Preparations to upgrade Port Moresby city ahead of the PNG Chief's 2028 entry into the NRL could cost up to K1 billion.

According to the National Capital District (NCD) City Manager, Mr. Ravu Frank, detailed scoping work is still being undertaken by engineers, and that final cost estimates are yet to be confirmed.

"I won't give the exact figures at this stage, but it could be somewhere between K500 million and K1 billion," he said.

Frank said funding discussions would involve the NCD Governor, the NCDC board, and the National Government.

"The Governor and the board will be looking for funding, and the Prime Minister has already indicated support," he said.

Further details on project funding and implementation are expected to be revealed once engineering assessments are completed.
