Poinciana Longicorn Beetle

A large longicorn (longhorned) beetle about 55 mm long with pale pearly brown smooth elytra. A darker brown thorax was textured with small depressions and short lateral spines. Antennae appeared to be a little longer than half the body length. The beetle's mandibles were prominent.
Flew into the lights outside our cabin and kept flying around the lit area - A riverside caravan park.
