What should I be aware of if moving to Mowbray Valley

Hi, I am thinking of moving to the area (away from busy Sydney). Can you tell me if the Mowbray valley has any flood or access issues and generally how restrictive it is, if so (I understand Port D gets cut off from Cairns from time to time in the wet season). Also if there is anything else you think I may need to be aware of. I have researched Port Douglas but looking at surrounding areas. Lastly what are the options for high school students. Thank you so much in advance and hope to see you there soon.
