Two businesses, one staircase. A fall on a heritage staircase can produce a claim against the owner, who controls the building, and against you, who chose to lead the group down it. Work health and safety law points the same way. Under the model laws, a business must make sure, so far as is reasonably practicable, that other people are not put at risk by its work, and that duty sits on the site and on you at the same time. So the two insurers may end up arguing about shares, and that's why owners ask for your certificate before they let you in.
What owners ask for. Heritage owners and precinct authorities can ask for a certificate of currency, their interest noted, and a clause where you indemnify them. On at least one specialist wording we place, the indemnity to others extension can cover a party your agreement requires you to indemnify, but only to the extent you'd have been liable anyway. Liability you take on purely because of the contract is excluded. A clause that has you release the owner, or give up the right to recover from them, can remove cover if you sign it without the insurer's prior consent. Our waivers and booking terms guide explains the difference between a waiver your guests sign and one you sign.
What is and isn't published. We checked what the larger heritage sites publish for visiting operators as at October 2026. Port Arthur's agent handbook and Fremantle Prison's group page both say the site's own guides lead tours inside the gates, and neither publishes an insurance requirement for visiting operators. The National Trust in Victoria publishes no insurance terms on its group bookings page. That doesn't mean nothing is asked. The requirements sit in each site's trade agreement, so ask for it early, send it to us before you sign so we can check how it sits with your insurance, and have your lawyer review it.
Buildings you can't change. Heritage protection can restrict new handrails, lighting and signage, so the physical controls you can add are limited. The underwriter will look at what you can control: briefings at the door, torches, route choice, group size and which rooms you skip in wet weather. Write those down, because they are your evidence if a guest is hurt.
'It was obvious' has limits. Old stone is uneven, and that is plain to anyone. But in Tapp v Australian Bushmen's Campdraft & Rodeo Association Ltd [2022] HCA 11, a NSW case about a horse event and not a tour, the High Court's majority said a risk has to be described at the same level of detail for the obvious risk defence as for the negligence claim. There, the risk was the specific deteriorated ground the organisers had been warned about, which was not obvious to the competitor. For a heritage walk, the practical point is to act on a specific hazard you know about, such as a broken tread or an unlit drop, during the tour and not after it. Our risk management guide covers how to record that.
