We are in planning stages for our trip next year. All dates are flexible but are thinking of visiting Cairnes/actually Trinity Beach mid to end of March 2019. I have read many reviews that there may be a lot of rain. So is it or is it not a good month to visit? We would like to visit the beach, do a GBR tour for snorkeling, and probably the rainforest. And, is swimming off of Trinity Beach NOT recommended because of "stingers"? Basically, a "laid back" trip. One more question--is there easy transportation between Trinity Beach and Cairns for just the day?
