Dunethin Rock  Dunethin Rock is a heritage-listed park at Dunethin Rock Road, Maroochy River, Sunshine Coast Region, Queensland, Australia. It was added to the Queensland Heritage Register on 5 February 2009. Dunethin Rock, a scenic reserve on the southern bank of the upper Maroochy River, is an important site associated with the development of tourism from the early 1900s on the Sunshine Coast, a major tourist region in Queensland. The two earliest pastoral leases on the northern bank of the Maroochy River were the Canando and Yandina runs leased by Daniel and Zachariah Skyring in 1853. Dunethin Rock, a prominent monolith on the southern bank of the river marked the shared southern boundaries of these runs. Land on the southern side of the Maroochy River was opened for grazing after 1860. In 1861 Edmund Lander leased the Mooloolah Back Plains, a run of with an outstation near Lake Dunethin, an inlet of the Maroochy River just north of Dunethin Rock. This outstation was abandoned by 1868. In 1862 John Westaway took up land east of Lander, known as Moolooloo Back Plains. Similar to the Skyring stations, the boundaries of the southern runs terminated on the Maroochy River in the vicinity of Dunethin Rock. During the 1860s the economy of the Maroochy region became increasingly geared towards extraction of the bountiful timber in the area. Brisbane timber merchant William Pettigrew, highly influential in the timber trade throughout south-east Queensland established a presence in the region, with depots on both the Maroochy and Mooloolah rivers later establishing a sawmilling complex near the Maroochy's mouth. In the mid 1860s Pettigrew transferred his Maroochy timber lease to James Low. Low established a timber depot opposite and slightly upstream from Dunethin Rock on the site of the wharf of the original Yandina run, opening a post office in 1868. The word Dunethin is of Aboriginal origin meaning the place of swimming trees, (dhu trees, yungathin, swim), a reference to the logs transported on the river in the area during this period. Until 1970, when Dunethin became the official name, the locality was often referred to as Dunethim. An early overland track from the depot to the Gympie diggings was built by Low and other timbergetters, accessed by a journey up the Maroochy River.
