Surfers Paradise itself has no airport today, so a lounge question tied to this specific code needs a quick correction before an honest answer can follow. SFP traces back to an older air-service arrangement for this stretch of Australia's Gold Coast, but Surfers Paradise as a place, the well-known beachside strip of high-rises and surf, does not have an operating airfield of its own for scheduled or private flights to use.
The real airport for this part of Queensland is Gold Coast Airport (OOL) at Coolangatta, a genuine commercial airport with scheduled domestic and international service, security screening, and its own terminal infrastructure, sitting a reasonable drive south of Surfers Paradise along the coast. This is where any actual lounge experience for travelers heading to or from the Gold Coast tourist strip would exist, not at the Surfers Paradise beachfront itself.
Gold Coast Airport carries airline lounge facilities for eligible travelers, including options tied to domestic carrier status and premium fares, though exact offerings and hours are the kind of detail that shifts over time, so check current facilities and your specific eligibility with the airline directly before you travel rather than assuming a fixed lineup. It is a smaller airport than a major state capital hub, so do not expect the scale of a Sydney or Brisbane, but it is a real, functioning gateway with its own airside lounge space, unlike Surfers Paradise itself.
If your trip is built around Surfers Paradise as a destination, remember that your actual flight, and any lounge access that comes with it, happens at Gold Coast Airport in Coolangatta rather than anywhere in Surfers Paradise proper. Plan your pre-flight time and lounge expectations around OOL, and confirm the airport's current lounge lineup, hours, and access rules directly with your airline before you travel, since regional airport offerings can change from one season to the next.
