The hire was actually through the sub-company, East Coast Car Rentals. The only bad thing was the base package which we initially signed up for had a mandatory $4,000 excess for ANY damage, even if at fault or not, plus a $1,000 hold. So we opted to upgrade for an extra $50-60 per day for the $0 excess and no hold.
That said no hidden fees but still charge 1000$ or insurance forcefully similar car NO FOR 6 people they give us 2 people car argument over argument rude etc
The service from Sixt in Cairns was brilliant, from the pick up service at the airport to the swift pick up of the car and drop off. All staff were very friendly and the car itself a dream to drive, making our experience in North Queensland brilliant.
