Hitchhikernick - Visited in June 2023 for 3 weeks. Average waiting time around 20 mins. Camped out in remote areas, left no trace and all worked out. The trash on the outskirts of main city and is ridiculousand stinks so you don't want to camp/saty there. Vavau is much nicer and wilder with the free roaming pigs. Supermarkets are available and the Chinese ones (quite a few) have all you need at affordable prices.

Was much cheaper than flying and may take time to hitch a boat , so didn't bother as ferry price was reasonable.
