studios; Ten (TVQ-10), Nine (QTQ-9), Seven (BTQ-7). The transmission tower for (ABC Brisbane) is located on the mountain, which also broadcasts television for multicultural station SBS and previously the community television station Briz 31.

Mount Coot-tha Botanic Gardens The Brisbane Botanic Gardens has a range of attractions featuring plants from different landscapes, including a tropical hothouse, a Japanese garden, an arid zone (plants from Central America and Africa), and a Pacific Island zone. The major exhibit is the display of native Australian plants (with emphasis on Queensland plants), featuring an artificial lagoon. Library Mount Coot-tha has a public library on Mt Coot-tha Road in the Brisbane Botanic Gardens operated by the Brisbane City Council. Unlike most public libraries in Brisbane which have general collections, this library holds a specialist collection about botany and astronomy and related topics reflecting its locations within the botanic garden and the Brisbane Planetarium also on the site. Walking tracks There are several popular walking tracks around Mount Coot-tha, one of which includes an art display comprising works produced by local Aboriginal artists. The tracks vary in difficulty, with most involving some uphill sections or steps. Tracks around Mount Coot-tha are often used by hikers training to walk the Kokoda Track in Papua New Guinea as the terrain and climate are considered similar. Mountain bike trails The Western side of Mount Coot-tha Forest or Gap Creek Reserve as it is known to the locals is a haven for Brisbane mountain bike riders. The establishment of a world class mountain bike trail network by the Brisbane City Council has created a diverse range of recreational experiences for off-road cyclists. The mountain bike trails at Mount Coot-tha have been assigned a grading under the International Mountain Bicycling Association, Trail Difficulty Rating System. The multi-use trails in Mount Coot-tha provide the least degree of technical challenge to mountain bike riders, however many of them are steep and loose. Riders are advised to pay special attention when riding over the erosion control banks (water bars) which have been the downfall of many a novice rider. The trail ratings provide a guide to the relative difficulty of each trail. The multi-use tracks are used by horses, pedestrians and mountain bikers. Each year
