One way Perth to Broome hire at Europcar $25 per day
This is interesting to my small mind.
Broome 2500km from Perth and the drive up there is one of those epic road trips with some absolutely beautiful scenery. This is obviously a cheap way for these guys to get their cars up to Broome for tourist season.
Lets say you wanted to take a reasonably leisurely jolly at 500km a day. Min 5 days rental so theres $125. Id assume one of these cars will get you about 500k on a tank so you'd be looking at 5 fill ups at lets say $70 a pop, theres $350.
Still works out cheaper than flying assuming there's two of you and you wanted to see a bit of WA.
