How do we compare Perth Airport SUV hire for a three-week Sunday-to-Sunday trip?

Book a cancellable rate if available, then recheck prices closer to travel without assuming they will fall. Consider whether a smaller vehicle still fits your bags and route.

Check the desk and shuttle hours for both Sundays before choosing an off-airport depot. A cheaper rate does not help if it cannot hand over the car after your flight.

Compare the whole rental with the same vehicle class, excess, kilometres, additional drivers and after-hours return conditions. Long hires can hide large differences in those terms.
