There is one catch - there is a large excess/deductible for damage to the rental car and third party property/vehicles - $3,300 for Hertz from non-airport locations (Cairns is 16% higher), plus a further $2,200 (+16% if from Cairns Airport) if no other vehicle is involved. It costs approx. AUD$25-50 per day to reduce the excess to a few hundred dollars or eliminate it altogether.

You need to a #1 Club Gold member. However, as previously mentioned, they waive the $60 fee to join. It's clearly visible on the Hertz website.
