This patch of Nephrolepis cordifolia (Fishbone Fern on Lord Howe Island, Tuber Ladder Fern on this site) was growing behind my hotel in the understory.
This beautiful fern was abundant along the trail, growing on the ground, from rocks, and even from a tree. Maybe Nephrolepis cordifolia (Tuber Ladder Fern)? It is supposed to be naturalized in this area, originally from farther north in Australia.
Tuber ladder fern, (Nephrolepis cordifolia) is a fern native to northern Australia and Asia. It has many common names including erect sword fern, narrow sword fern and ladder fern, fishbone fern, and herringbone fern. It is similar to the related fern Nephrolepis exaltata.
