So, I'm calling off my regular French Australian timeline, but I'm thinking of starting a replacement TL with the following premise: The French establish a penal colony in Western Australia around OTL's Perth in the 1820s before the British can. From my research, I've found that the Coastal Plain has very sandy, infertile soil (except for the banks of the Swan River), but that areas further inland is well-suited for wheat growing and livestock raising. So, how might a French colony in Western Australia that began as a penal colony develop? What types of convicts would be sent there, and how many? How many free settlers would settle in Western Australia, and of course what would be the name of this colony? This will be a TL soon, so any help would be greatly appreciated.
