Opposition leader Don Polye revealed this at a press conference in Port Moresby.
However, the venue has not been mentioned.
He said the main aim of the camp was to give chance to other members of Parliament to join them and throw down the O'Neill-Dion government.
Polye said he is confident that MPs will be joining them within the five days.
Meanwhile, Parliament have been set to reconvene this Friday at 2pm after the Court ordered the Speaker Theo Zurenuoc to recall parliament within 5 days.
