congratulations.
i was married in fiji last year at the naviti resort on the coral coast, we had a lovely sunset wedding overlooking a remote island on the balcony of the bar at the resort.
i even had a professional photographer, he was really well priced, i think $500 for the whole day and all photos on CD for me to print as i needed.
the wedding co-ordinator at the resort was great we arranged it all via email, was $1600 fijian for the whole package flowers were $120 for huge boquet of frangipannis.
we took over my dress, no issues with the plane they took it up to buisness class and kept it hanging in teh coat cupboard.

the resort is great for kids, we hardly saw DS he spent all his time with the kids club.

we did dinner at the chinese resterant was sooo yummy and all included with our accomidation package.

i had hjair and make up done by the girls there was $50 bucks for both.

i have a stack of photos on my face book page if you want to look.
any questions just ask or send me a pm.

yes it is legal and recognised within australia. we had to send some paper work over and get a single status certificate to say we are not married to someone else lol
