Pro vice-chancellor academic for UPNG, Professor Mange Matui, said this year, students are paying a compulsory fee of K2,900.
Next year, that fee will dramatically increase.
He said the new fee will be put out in the daily newspapers.
Professor Matui said the university is currently struggling and blamed the Government for this.
He said every year, the university submits about K150 million, which is the normal budget covering its operational costs, but every year the Government gives only K47 million.
The Professor also indicated more budget cuts for the university, from the 2018 budget.
