Daintree
River
The reputation that Daintree has for seeing wildlife was established by wildlife viewing boats like this one.
Large enough to handle an eco-tourism group but small enough to access the more interesting parts of the Daintree River system. (This is where the 50 seaters cannot go because of their size and crippling speed restrictions.)
Rarely do these vessels come up for sale. They are a delight to drive and can be used privately and also used for filming nature documentaries for which the Daintree is famous.
