Nine Mile Beach is a remote, undeveloped coastal beach located outside any settlement within the Byfield National Park in Livingstone Shire. The beach is characterized by a 100-meter-wide intertidal to low tide sandy beach, backed by a 50-meter boulder beach and flanked by wide rock platforms. The point forming the southern boundary of the beach is Water Park Point, an irregular, 80-meter high headland. There is no formal vehicle access to the point or the beach, and the area has no development. Public access is available without amenities. The beach is adjacent to a road, but parking specifics are not detailed. The overall character is one of a pristine, untouched landscape. For paddlers launching from shore, the carry from parking to the water's edge involves navigating a rocky backshore and boulder beach. Wave height averages about 0.4 meters, typically spilling across a low gradient bar, though the adjacent Little Corio Bay picks up most swell and usually has a beach break. The water temperature averages around 21 degrees Celsius in the warmer months and 19 degrees in cooler periods. The area is known for environmental concerns related to vehicle traffic on the beach. Camping permits for the area are phasing in a condition for campers to bring portable toilets. Notable sights for a paddling trip include the views from Water Park Point and the headlands. The beach faces northeast, making it exposed to prevailing winds and swell from that direction.
