The matchbox bean is well known for their seeds which are used by aborigines and artists for seed jewellery. These seeds are true seafarers like the Nickernut (Caesalpinia bonduc) and are often washed up the shore where they germinate and begin their life as a climber in coastal strandline vegetation (although they also do get a bit inland.
These climbers are some of the most impressive of the pea family, and their climbing trunks can become as thick as the thigh of a man (or thicker). They also have some of the largest pods in the pea family (the largest being Entada gigas, which is not found in FNQ).
Check out the stoutness of the pod.
The leaves are compound and each secondary pinna having ~8 leaflets. In the similar Entada phaseoloides the secondary pinna have ~4-6 leaflets.
