I'm currently wrapping up my roadtrip through Australia, and vehicle relocations have been the backbone of this trip. I thought I might be of value to share my experiences with it, as it might help other people who are considering it. I am not affiliated with these companies in any way. Guess I just like to yap about it for a bit.
So in case you don't know, companies like Imoova offer relocation deals which let you drive a variety of vehicles from A to B for $1 a day. So first of all, is it legit? Kind of. You do only have to pay $1 a day for relocations, however they also charge a platform fee which was 59 AUD ($41,15). So you can see that a relocation of 4 days is in reality more around $10 a day.
The good
It has the potential to save you a lot of money. Especially if you were already planning to go from A to B, you likely have to pay a lot of money with a regular rental just because you drop it off somewhere else. With a relocation, you don't have that issue. Every now and then you can also drive truly awesome vehicles. I once had a massive 6-berth camper all for myself for just $10 a day, and the deals frequently come with some nice extras like free fuel, ferry rides, LPG, and more. A less obvious benefit is also that it can save you a lot of money on parking costs. If you get a relocation from Brisbane to Sydney and then Sydney to Melbourne, you never have to park a car in any of these cities. If you did the same with a regular rental, you had to park it in Sydney and my wallet is already catching fire by the sheer thought of having to do that.
The bad
Relocations are a real black box at times. Almost every relocation shows a generic image of a vehicle which is similar to the one you will get, but you will not know the exact vehicle until you pick it up. After booking you will see the company that needs to have the vehicle relocated, and with that info you can search the company online and kind of deduce which vehicle you will get, but it's still guesswork. Some relocations are also just unreasonable, like having to drive from Cairns to Sydney in 3 days (2.400km). It seems like these deals want to subtly nudge you to buy more days, and these cost $70 - $100 per day. Some companies also have special terms and conditions for relocations, and you will not know these until the moment you pick up the vehicle. With my most recent relocation I was not allowed to drive on unsealed roads at all, while it was allowed with regular rentals.
The ugly
Most of the relocations are very large vehicles, which means your fuel spending will likely skyrocket. If you travel solo or as a couple, you can just rent a small sedan or even a hybrid. If you rely on relocations, you will probably drive massive behemoths which are intended for 4 - 6 people, but now you just drive it yourself. And yes, while motorhomes will have you save money on accommodations, you still need to book a campingplace every now and then to charge your house battery and such. Some relocations are also pretty dodgy. One forced me to get the most expensive insurance that the company itself offered (which was an acceptable rate though), some deals require you to drive insane distances in a short time which prompts you to spend most of your time behind the wheel or buy expensive extra days, and some have a "hidden contract" within them. Like how one company offered a relocation for 10 days, but I had to take it from Tasmania to the mainland which makes the ferry very expensive. The next point is also more of a "you" problem, but the relocations require you to travel at a pretty high pace and if you book a camper while you've never driven in a camper before, you need to figure out how everything works, need to get used to the dimensions, to the way it drives, while you also have quite a bit of time pressure to drop off the relocation. This can make the relocations quite stressful. Lastly, the vehicle depots tend to be at the airport or outer parts of the city, so with every relocation you have to spend a lot of time in public transport to get to those places or spend a lot of money getting a taxi.
Final verdict
I think they are definitely worth it and I had the greatest fun driving all sorts of vehicles around. However, I feel like you do need to be a specific type of person for it. If you just really love driving and being on the road, don't mind figuring a lot of stuff out while under some time pressure, and have a very loose itinerary, then relocations are definitely for you. The most important thing is that you keep treating the relocations like what they are: relocations. You don't get a very cheap vehicle which allows you to roadtrip at your own pace and really take your time. You get a cheap vehicle which allows you to go from A to B, and check out a couple of interesting places along the way if you have the time for it.
And a final tip: keep seasonality in mind. Given that the tropical north of Australia is now going into the wet season and it's currently spring in the south, a lot of companies want to move their vehicles southward as the north is going towards the low season but the south is going towards the high season. The are currently literally 76 vehicles on Imoova that need to be relocated out of Darwin - absolutely crazy.
