The Kingdom of Tonga is unique in the Pacific ... it was never formally colonised and it's the only country in the region still ruled by Royalty. In the Pacific's only monarchy, Tania Nugent got the chance to meet not one but two charming Tongan Princesses.

Hon. Salote Lupepau'u Salamasina Purea Vahine Arii 'o e Hau Tuita: My name- it's quite long... Salote Lupepau'u Salamasina Purea Vahine Ari'i o'e Hau Tuita.

Hon. Titilupe Fanetupouvava'u Tu'ivakano: My name is Fanetupouvava'u Tuita.

Hon. Lupepau'u: I am the eldest daughter of Salote, Her Royal Highness Princess Salote Mafile'o Pilolevu Tuita and Lord Tuita.

Hon. Fanetupouvava'u: I am the second daughter of her Royal Highness Princess Pilolevu and Lord Tuita.

Tania Nugent: Sisters, Princess Lupepau'u and Princess Fanetupouvava'u, are nieces to the King of Tonga. I met up with them for an interview at the Palace Office right next to the Royal Palace in Tonga's capital Nuku'alofa, and it didn't take long before we got on to girl talk - family, dating and marriage.

Hon. Lupepau'u: The first twenty in line to the throne have to marry within the nobility.

Tania Nugent: Were your marriages arranged?

Hon. Fanetupouvava'u: Yes.

Hon. Lupepau'u: Ideally you're supposed to be given a person or chosen a person

Tania Nugent: Do you still need the Kings approval for that?

Hon. Lupepau'u: You need a document where he consents to it and then the marriage can proceed. It's a whole traditional cultural process, if you are a certain rank, then the courtship is prolonged. There is a lot of going back and forth between various suitors, not just the one.

Hon. Fanetupouvava'u: And you don't really have to know them before you get married, but there is a Tongan way of dating, but it's very public and it's in front of your family.

Hon. Lupepau'u: Aunts, uncles, cousins.

Tania Nugent: Lupepau'u was married in 2003 and Fanetupouvava'u in 2007.

Hon. Fanetupouvava'u: My husband name is Kiu. They approached the traditional way as well and my family considered it and found it favourable, took it to the King and he gave his consent, and then we set the date. Since then we have been very good friends.

Hon. Lupepau'u: I was married.

Tania Nugent: Are you divorced?

Hon. Lupepau'u: Yes.

Tania Nugent: Is that a common thing? It must be quite controversial.

Hon. Lupepau'u: Very controversial. It hasn't been done in our family before. I think I'm the first

Hon.Fanetupouvava'u: Our family doesn't really. It's not quite acceptable to be divorced.

Tania Nugent: So you managed to do that?

Hon. Lupepau'u: Yes.

Tania Nugent: With no problems? Or problems?

Hon. Lupepau'u: Well I think it had a lot to do with my character. I didn't see something working and I wanted to fix it. So I fixed it on my own. It's acknowledged but we don't seek to promote it. It's the last resort. I think.

I think we are very lucky we have had very understanding parents. I think more understanding than most traditionalist parents. They have been very, very supportive and they're happy that we are happy, that's the main thing.
