Rex Beach is generally suitable for swimming, though conditions vary with tides and seasons. The beach is sheltered but lacks lifeguard patrols, so swim at your own risk and stay alert to changing conditions. During summer (November-May), marine stingers are present in Far North Queensland waters, so consider wearing protective clothing or swimming in designated netted areas at nearby beaches. Check local conditions before entering the water, avoid swimming alone, and be mindful of currents, especially during outgoing tides. The calm, protected nature of this small beach typically makes it gentler than more exposed coastlines.

Rex Beach can be enjoyed year-round, though the dry season (May-October) offers the most comfortable weather with lower humidity, minimal rainfall, and temperatures around 25-28°C. This period is ideal for beach activities without the intense heat. The wet season (November-April) brings tropical showers, higher humidity, and warmer temperatures, but also fewer crowds. Mornings and late afternoons are best for avoiding midday heat regardless of season. Marine stingers are most prevalent during wet season months, requiring extra precautions. Being less crowded than Four Mile Beach, Rex Beach offers a peaceful escape during Port Douglas's peak tourist season.

Rex Beach is located in Port Douglas, accessible from the southern end of town. From Port Douglas centre, head south along Captain Cook Highway; the beach access is near the Rex Lookout area. Limited street parking is available along Wharf Street and nearby residential streets—arrive early during peak season for better spots. The beach is a short walk from parking areas. It's easily reachable by car (about 5 minutes from central Port Douglas), bicycle, or on foot if staying nearby. The relatively hidden location means it's quieter than Four Mile Beach but requires knowing where to look.

Rex Beach has minimal on-site facilities, reflecting its quiet, local character. No cafes or restaurants are directly at the beach, but Port Douglas town centre is just minutes away, offering numerous dining options, supermarkets, and shops. Public facilities are limited, so plan accordingly. For accommodation, Port Douglas provides extensive choices from luxury resorts to budget hotels and holiday apartments, most within a short drive. The nearby Port Douglas Marina precinct has restaurants and amenities. Visitors should bring their own supplies (water, snacks, shade) as this beach lacks commercial development, contributing to its peaceful, unspoiled appeal.

Locals favour Rex Beach for its tranquility and lack of crowds compared to the popular Four Mile Beach. This smaller, more secluded spot offers a peaceful alternative away from tourist bustle, ideal for quiet walks, sunrise watching, or simply relaxing without large groups. The intimate size creates a more personal beach experience. While it lacks the extensive facilities of Four Mile Beach, that's precisely the appeal—a genuine, unspoiled coastal setting. Locals appreciate having this hidden gem where they can escape commercialization while still being close to Port Douglas amenities, making it perfect for those seeking authentic, low-key beach time.
