Two members of the crowd, gathered at the main entrance point, told this newsroom that they arrived in the city from Simbu and Enga over 5 days ago.
Police and PNG Defence Force personnel are stationed around the grounds to make sure things do not get out of hand.
Seating at the grounds is estimated to be less than 6,000. However, between 6,000-7,000 people are expected while most of them will sit or stand on the lawn.
