Most people figure the hard part of planning a Great Ocean Road hire is finding a good rate. Lock that in, and the budget sorts itself out. What catches people off guard is that the rate on the search results page is just one part of the cost, and sometimes not even the biggest part by the time pickup day arrives.
Every charge that gets added on top has a real reason behind it. None of it is hidden. When you’re focused on locking in a good daily rate, the rest of the booking screen doesn’t always get the same attention, and that’s usually where the bill starts creeping past what you had in mind.
Base hire covers the car and basic third-party insurance. A protection package upgrade, extra kilometres, a young driver surcharge, and a second driver fee all sit separately on the booking. Airport transfer fees at Tullamarine and the Gold Coast get added on top, too. By the time you tally it all up on a five-day trip, the extras can quietly overtake what you actually paid for the car itself.
Standard hire comes with a $5,000 excess. That’s what you’d be liable for out of pocket if the car got damaged, regardless of who was at fault. Most people doing a longer coastal trip want that number lower, and there are three paid tiers that bring it down while also increasing the daily kilometre allowance:
| Package | Daily Rate | Excess | Km Per Day |
| Standard | Included | $5,000 | 200 km |
| Basic | $13 | $2,200 | 300 km |
| Safest | $23 | $1,100 | 400 km |
| Premium | $33 | $385 | Unlimited |
The kilometre side of this matters as much as the excess for a Great Ocean Road trip. Otway’s back roads and detours off the main highway eat through the allowance faster than people expect, and every kilometre over the daily limit costs 30 cents. Paying the upgrade upfront usually works out better than paying overage at the end.
Drivers under 25 attract an extra $16.60 per day, on a five-day trip, that’s $83 per young driver on the booking, on top of everything else. It applies to each person under 25 listed as a driver, not just the primary hirer.
Putting a second person on the agreement costs $20 per driver as a one-off fee. Not per day, just a flat charge at pickup. If two people are taking turns at the wheel, the second driver has to be listed. Getting this sorted before leaving the depot saves issues later.
Cars go out full and need to come back the same way. If the tank is short on return, the hire company refuels it at $4.35 per litre. You’ll pay noticeably more per litre than you would at any servo along the way. Just fill the tank before you return it, takes five minutes and keeps that charge off your final bill.
The Melbourne and Gold Coast depots aren’t located on airport grounds, so getting to and from them does involve an extra step. Tullamarine has a transfer service running all day and night at $22.50 each way. At Gold Coast, you’re looking at airport parking for pickup and drop-off, starting at $8 for up to 30 minutes. If you can get yourself to a city depot, you skip this cost altogether.
Melbourne’s toll network is cashless and runs on linked accounts. Hire cars without a registered e-TAG attract a $4.40 admin charge on top of the actual toll, for each day a tolled road was used. Parts of the route toward the Great Ocean Road do pass through tolled sections, so it’s worth mapping your drive beforehand. Any traffic fines picked up during the hire period also carry a $48 admin fee on top of the infringement cost.
The standard cleaning fee if the car comes back in worse condition than it left is $55. If it’s been smoked in, that goes to $110. Coming back over an hour late without calling ahead to arrange an extension gets charged as a full extra day. None of these is difficult to avoid; they just need to be remembered.
Take a straightforward five-day trip: two people sharing the driving, one of them under 25, picking up at Melbourne Airport, choosing the Safest package for a route that includes some Otways roads.
| Item | Calculation | Cost |
| Base hire | $35/day x 5 days | $175 |
| Safest package | $23/day x 5 days | $115 |
| Young driver surcharge | $16.60/day x 5 days | $83 |
| Additional driver | Flat fee | $20 |
| Airport transfer (both ways) | $22.50 x 2 | $45 |
| Total | $438 |
Every charge in that total is published and available before the booking is confirmed. The issue isn’t that the costs are hidden. It’s that the headline rate doesn’t show them, and most people don’t work through the full breakdown until they’re asked to at the counter.
None of these charges is buried in fine print. They’re all on the booking screen before you confirm. The difference between an expected bill and a surprising one usually comes down to whether you spent five minutes reading through the full breakdown or skipped straight to the confirmation button. Check the kilometre allowance against your planned route, factor in anyone under 25 on the booking, and fill the tank before you return it. Small things, but they add up.
