Seaside at Moana - Statesman Homes. Some queries

HI all,

This is my first time on this forum and thanks in advance to anyone who can provide any advice

We're in the process of signing for some land at Seaside at Moana - Adelaideand putting a house on it with Statesman. The process with our sales advisor has, so far, been very good and we've been very happy. However, the contracts that they're giving us are leaving us less happy. Has anyone here signed the land contract for seaside at Moana? We had several queries we wanted to address and have been waiting weeks for a response. Been told today that the build manager says that they are still working through our 6 points.. that he also said that "the contract won't change much... they sell hundreds of houses" etc.
There are clauses in there that we're not happy with. Clauses about the land size being able to change 5% either way before we see a pro-rata on the price, etc. The other clauses are about time delays etc... and aren't too major..

Then we saw the build contract, took it to a solicitor who pointed out that the contract is HEAVILY weighted in their favour, more so than a standard HIA contract. He told us that he wouldn't be surprised if they didn't take advantage of their clauses to make the cost more as we go along. We can't afford that... we're on a tight budget. We've also been told that they won't make changes to their contrat.
They seem totally unfriendly to customers and totally over protective of themselves... And I"m starting to doubt my relationship with them as a company as a result. They are coming across as unreasonable and possibly sne aky...

So... I guess i'm looking for other people who are building with Statesman or who are building at Seaside at Moana and might be able to reassure me.

Did you lay a slab up there... was your quote right? Did you end up paying more?
Have you bought and built with Statesman and have they used the clauses in the contract to make you pay more?
Have they ever listened to a consumer and adjusted the contract?

I'm starting to consider pulling out of either building with them or buying the land full stop. Which is a shame because We were all very excited about this project. Maybe building with Rossdale who do seem to offer an actual fixed price contract might be better for us?

Make me feel better.... so I can just the sign the contract and go with it!! lol
