Welcome to the Bunnings Workshop community @makhan006. It's brilliant to have you join us, and many thanks for your question about custom wardrobes.
There is no service to have a completely custom wardrobe manufactured. However, there are a myriad of different pre-made modular wardrobe elements you can easily put together to fill your space. You might like to let us know the area's dimensions you're working with and possibly add some images to the discussion. That way, our helpful members would be better placed to assist you with planning the layout.
