Papua New Guinea's new budget has been slammed by organisations such as the Institute of National Affairs, which says an increase in company tax could mean that very soon there will be very little for the Government to tax.

The Government also wants to develop other sectors of the economy and hopes that improvements to infrastructure will help it achieve this.
It is planning a major rebuild of the critical Highlands Highway, as art of a 50 million US dollar package to improve the nation's roads.
