4 houses in Port Headland would get you 5 in Broome for the same $'s or less. You would have a better chance attracting and retaining staff at Broome than the Port.
You also have to include medical staff into this equation. Whilst pilots will go and live anywhere if you show them photos of a flash jet, you can have a reasonable amount of difficulty finding Emergency Medicine Specialists to go and live in remote towns. Broome would be much easier to attract medical staff than just about any other town in the region. It also has much better airline connections.
