Do it interstate!! We got married in NT and only had our parents andour one sibling each with a few friends who were local. It was beautiful, we used a celebrant in the park , can't remember the cost sorry then walked across the road to a big hotel and had a buffet meal in a seperate part of the dining room. Guests paid for their own alcohol. Mum made my dress cause I was 5 months pg! A lady at work's friend made the cake for $50, my brother is a wedding photography so we were lucky we got fantatsic photos free!
I am in Sydney and on school holidays so if you need anyone to do any phoning or enquiring for you I would LOVE to!! I can ask my brother questions too since he is in the business, although he is wayyy too expensive for nayone on a budget LOL
