Help is on the way for those regions struggling to cope with booming tourist numbers.

A plan to introduce a tourist tax of $25-$35 has been unveiled by the government.

As much as $80 million is expected to be generated from the levy but visitors from Australia and most Pacific island countries will be exempt. 

The money will go towards funding badly-needed tourism infrastructure around popular hotspots overrun by visitors, freedom camping facilities and conservation projects.

The tax is likely to come into force in the second half of next year.
