It rings the driver.

Parag, the person who will be driving. One number, +61 435 162 311, takes both calls and WhatsApp, and WhatsApp is the quickest way to change a booking that already exists. Anything easier typed than said — a complicated itinerary, procurement paperwork, an invoice query — goes to bookings@ospipo.com.au. There is no switchboard, no ticket queue and no first-line support reading from a script.

Usually 30 minutes, and within 2 hours at the outside. Confirmation arrives as a personal message from Parag rather than an automatic green tick, and until it lands what you hold is a request rather than a confirmed job, which this site says plainly instead of hoping you do not notice. Nothing is charged in the meantime, no card details are taken, and cancelling before pickup costs nothing.

Call or send a message rather than using the form. 3 hours is the least notice the booking system accepts, and below that the answer depends entirely on where the car is standing at that moment, which only a person can tell you. Short notice does not move the price — Sydney Airport to Wollongong stays a fixed $341, with tolls, GST and the NSW Passenger Service Levy inside it.

Two addresses, a date and a time. A name and a contactable mobile for whoever is actually travelling completes it, and an assistant, an office manager or a relative can supply those on a passenger's behalf. For an airport run, add the flight number: not required, but it is what lets the pickup follow the aircraft instead of the timetable. Anything awkward to type — a gated estate, a hospital entrance — is easier said on +61 435 162 311.

Yes, at any hour, every day of the year. A question at 4am gets an answer at 4am, because the phone on +61 435 162 311 belongs to the chauffeur rather than to an office that opens at nine. The hour does not move the money either: a 4am departure is invoiced at the same published figure as a midday one, with no after-hours loading of any kind.

Complaints go to Parag, on +61 435 162 311 or bookings@ospipo.com.au, because there is nobody else in this business for them to reach. That is the cost and the point of a single operator: no queue to escalate through, and no answer written by somebody who was not in the car. Where the issue concerns compliance rather than service, the NSW Point to Point Transport Commissioner regulates booking service providers and can be contacted independently.
