S24

S24 is an Australian 24‑hour fuel and convenience store brand (often short for “Store 24”) operating service stations in multiple states and territories, including Queensland, Western Australia, the Northern Territory and New South Wales. Many S24 sites retail Shell‑branded fuel and are part of Viva Energy’s broader convenience and mobility network, which also includes brands like OTR and Reddy Express. Viva Energy Australia Limited, headquartered at 720 Bourke Street, Docklands, Victoria, supplies the fuel and oversees customer support for its service station network.([m.xxshagua.com](https://m.xxshagua.com/contact-us?utm_source=openai)) In addition to unleaded, premium and diesel products, selected S24 locations may offer LPG, car wash facilities, basic groceries, snacks, drinks and other travel essentials, with many sites operating 24/7 for card and contactless payments.([coparking.ch](https://coparking.ch/en/Australia/parking/8865?utm_source=openai))

A charge from “S24”, “S24 Calliope”, or a similar S24 location name on your bank or card statement typically relates to in‑person purchases made at one of these service stations. This can include pay‑at‑pump fuel transactions, in‑store purchases (food, drinks, basic groceries, automotive products), car wash services, or a combination of these on a single receipt. Some card issuers will first show a temporary pre‑authorisation amount when you start a pay‑at‑pump transaction, which can be a small test amount (e.g. $1) or a higher hold (often between about A$50–A$150) and later replace it with the actual final fuel total once the sale is completed. It’s also possible to see multiple S24 line items if you made several separate purchases on the same day, used a fleet or fuel card that batches transactions differently, or if a pending authorisation and the final charge briefly appear at the same time.

If you’re unsure about an S24 charge, start by matching the date and amount with any recent fuel stops or convenience purchases in Australia, and check your physical or emailed receipts if you have them. Many S24 sites print the exact site name, address and phone number on receipts (for example, S24 Calliope lists a local contact number), so you can call the station directly to confirm what was purchased.([coparking.ch](https://coparking.ch/en/Australia/parking/8865?utm_source=openai)) For broader billing questions, fuel quality issues or if you can’t reach the site, you can contact Viva Energy’s customer service team for service‑station customers by calling 13 16 18, Monday to Friday, 8am–8pm AEST, or by using the “Service Station Customers” contact form or email on the Viva Energy website.([vivaenergy.com.au](https://www.vivaenergy.com.au/contact/service-station-customers?utm_source=openai)) Ask your bank or card issuer to clarify any temporary holds or duplicate pending items; most pre‑authorisations and duplicate errors drop off automatically within a few business days, but if a transaction appears to have been processed incorrectly, you can request a refund review from Viva Energy or dispute the transaction through your bank if needed.
