Last updated 2026-08-16 · SmashX Concierge Team · Sydney, NSW

Almost everything that happens after an accident depends on one question: who caused it. This guide sets out plainly what changes for you in each case, including the very common situation where nobody is certain yet.

If another driver was at fault

This is the strongest position to be in. Because the loss was caused by someone else, the costs of putting you back where you were are generally recoverable from them or their insurer.

If you were at fault

Your own policy determines what happens. Comprehensive cover generally pays for your repairs after you pay your excess.

A hire car is only provided if your policy includes that benefit, which is often an optional extra rather than standard.

Repairs are usually directed through your insurer's network unless your policy includes choice of repairer.

If nobody is sure yet

This is extremely common and it is not a reason to delay getting help. Fault is decided on the evidence, not on what either driver believes at the scene.

Photos, witness details, the position of the vehicles and the damage patterns all feed into that assessment. The sooner those are gathered, the better the outcome tends to be.

If you are unsure, say so. It is far better than guessing and it does not weaken your position.

Where people lose time

The most common delays are not caused by repairs. They are caused by missing information, particularly the at fault driver's insurer and claim number, and by waiting to see what the insurer does next.

The practical difference

In a not at fault claim, the goal is recovery of your losses from the party responsible. In an at fault claim, the goal is making the most of the cover you have already paid for.

SmashX handles both, and the first step is the same either way: tell us what happened and we assess it from there. Eligibility and circumstances apply.

Common questions

What if I think I might be partly at fault?

Fault can be shared, and it is assessed on the evidence. Do not assume you are responsible before the circumstances have been reviewed.

Do I get a replacement car if I caused the accident?

Only if your own policy includes a hire car benefit, which is frequently an optional extra rather than standard cover.

Does being not at fault mean I pay nothing?

Where you are not at fault and eligible, costs are usually covered with no upfront payment in most cases. Eligibility and circumstances apply.
