Travel Recommendations:
Flight: Ensure your flight destination is to Kota Bharu airport. A flight from KLIA/Subang Airport will reach Kota Bharu airport in about 45 minutes. Then another 45 minutes from the airport to Kuala Besut Jetty by land transport. 
If you wish to come by bus, you can take a bus that stop at Kuala Besut Jetty or Jerteh. If you are at Jerteh, you need more 10 to 15 minutes to reach the Kuala Besut Jetty.
Highly recommended to book an early flight to Kota Bharu as the first trip from Jetty to the Island is at 11am. More importantly to book a return flight no later than 3PM to avoid unnecessary rush.
about boat transfer:  Boats leave Kuala Besut (Jetty)  for Perhentian from 8 am to 4.30 pm and return at 8am, 12pm and 4 pm. The boat trip takes half an hour but allow for one hour for planning travel times.
