The places Sydney clients ask for are managed by several different bodies, and each runs its own permit. The Botanic Gardens of Sydney sell a two-hour wedding and engagement photography permit (opens in a new tab) for the Royal Botanic Garden and The Domain, the Australian Botanic Garden at Mount Annan and the Blue Mountains Botanic Garden at Mount Tomah, for shoots between 8am and 5pm. At the Royal Botanic Garden it doesn't cover indoor venues such as The Calyx, Palm House or Lion Gate Lodge, and a shoot running past closing moves across to The Domain. Centennial Parklands has its own two-hour permit (opens in a new tab), which isn't needed if the ceremony is booked with the Parklands. Out west, Greater Sydney Parklands says all wedding photography needs a permit (opens in a new tab) in Parramatta Park and Western Sydney Parklands, while Sydney Olympic Park issues a day permit (opens in a new tab) for celebrations and portraits photographed as a business, from sunrise to sunset, for groups of up to 12.
Around the harbour, Place Management NSW issues filming and photography permits (opens in a new tab) for The Rocks and the Circular Quay promenades, Darling Harbour, The Goods Line, Ballast Point Park and several Pyrmont foreshore parks, and asks applicants to hold at least $20 million of public liability cover. In national parks, including Sydney Harbour National Park, Royal National Park and Ku-ring-gai Chase, the National Parks and Wildlife Service requires approval for commercial photography (opens in a new tab); wedding photography generally fits its streamlined small-scale category, which allows one camera operator and one assistant and no drones.
None of this needs reciting on your website, and the rules and fees change, so we'd link to each agency's page rather than copy its terms. What helps is being clear about your own process: which locations you suggest, whether your package includes the permit, and how much notice you need to arrange one. That one line per location saves a round of emails with every couple who has their heart set on the Botanic Garden or Mrs Macquarie's Chair.
Aerial work needs the same care. CASA lists Sydney Harbour and surrounding areas (opens in a new tab) (restricted airspace R407 A/B), and flying within 5.5 km of a controlled aerodrome such as Sydney Airport, among the operations that need a flight authorisation. Greater Sydney Parklands bans recreational drones on its land and requires approval, an operator's certificate, a pilot licence and $20 million of cover for commercial flights (opens in a new tab), and says drone filming in Parramatta Park is generally not permitted. Place Management NSW generally doesn't allow drones in the areas it manages. If you offer aerials, the site should say where they're possible and on what basis.
For brand and commercial photographers who cast children, NSW has a separate rule: the Office of the Children's Guardian says anyone who employs children under 16 for still photography or modelling must hold an authority to employ children (opens in a new tab). We don't advise on it; the official page is the place to check. We're a web design team in Adelaide working with Sydney businesses by phone and email, which suits photographers who spend weekends on shoots: send us your galleries and packages, and the draft comes back as a link you can look through between edits.
