澳大利亚采购需求：家禽养殖场、钢结构仓库、集装箱房屋、洗手站、移动厕所

I'm exploring prefabricated modular homes for a couple of projects in Western Australia. I'm particularly keen on a 3-bedroom, 2-bathroom model. Could you share base pricing, available floor plans, standard inclusions (like kitchen and bathroom specs), compliance docs for Australian building codes, estimated lead time for delivery, and shipping costs to Perth? Additionally, I have a development site for up to 9 homes and would like info on bulk pricing and support for that scale. If you have completed projects in Australia, especially in WA, I'd love to see photos or get references. Looking forward to your response!
