Question: What south-eastern river that orginates from Mount Kosciuszko and has Brodribb River as a perennial river?
Context: The Snowy Mountains, known informally as "The Snowies", is an IBRA subregion and the highest mountain range on the continent of mainland Australia.  It contains the Australian mainland's highest mountain, Mount Kosciuszko, which reaches to a height of 2228 m above sea level.  The range also contains the five highest peaks on the Australian mainland (including Mount Kosciuszko), all of which are above 2100 m .  They are located in southern New South Wales and are part of the larger Australian Alps and Great Dividing Range.  Unusual for Australia, the mountain range experiences large natural snowfalls every winter.  Snow normally falls the most during June, July and early August.  Therefore, most of the snow usually melts by late spring.  The Tasmanian highlands makes up the other (major) alpine region present in Australia. Charlotte Pass (often erroneously referred to as Charlotte's Pass), elevation 1837 m , is a location, snow resort and village in the Snowy Mountains of New South Wales, Australia.  The pass is located in the Kosciuszko National Park where the Kosciuszko Road crosses Kangaroo Ridge.  Charlotte Pass is the closest village to Mount Kosciuszko. Cootapatamba Hut is a survival shelter in the river valley south of Mount Kosciuszko, in the Kosciuszko National Park, New South Wales, Australia. Lake Albina Ski Lodge was built overlooking Lake Albina in the Kosciuszko National Park of Australia, by The Ski Tourers Association, (later renamed The Australian Alpine Club).  In 1952 the first Albina Summer Slalom Cup was held, taking advantage of the seasonally unusual snow conditions.  Summer time ski events continued for at least another 3 years on either Mount Kosciuszko or Mount Townsend.  The National Parks and Wildlife Service (NPWS) required the club to vacate the lodge in 1969, and it gradually became a ruin.  It was finally demolished by NPWS in 1983 . The Little River is a perennial river of the Snowy River catchment, located in the Alpine region of the Australian state of Victoria.  It is one of two rivers of the same name that are tributaries of the Snowy River, the other being the Little River (Kosciuszko National Park). The Australian Alps Walking Track is a long distance walking trail through the alpine areas of Victoria, New South Wales and ACT.  It is 655 km long, starting at Walhalla, Victoria and running through to Tharwa, ACT near Canberra.  The track weaves mainly through Australian national parks, such as Alpine National Park and Kosciuszko National Park, though it is not exclusively restricted to national parks.  It ascends many peaks including Mount Kosciuszko, Mount Bogong, and Bimberi Peak, the highest points in N.S.W., Victoria, and the A.C.T. respectively.  The AAWT crosses exposed high plains including the Victorian Bogong High Plains and the Main Range in NSW.  To walk the whole trail can take between 5 and 8 weeks.  Food drops or a support crew are necessary, as the trail passes through no towns, although it passes close to the ski resorts of Mt Hotham, Falls Creek, Mt Baw Baw, Thredbo, Charlotte Pass and Perisher. The Thamirabarani River (Porunai) (Tamil: தாமிரபரணி(பொருனை)) is a perennial river that originates over there .  It flows through Tirunelveli and Tuticorin districts of the Tamil Nadu state of southern India into the Gulf of Mannar.  It was called the Tamraparni River in the pre-classical period, a name it lent to the island of Sri Lanka.  The old Tamil name of the river is Porunai.  From the source to sea, the river is about 128 km long and is the only perennial river in South India.  It is the only river in India that flows towards North direction.  However it changes to South direction later. The Brodribb River is a perennial river of the Snowy River catchment, located in the East Gippsland region of the Australian state of Victoria. Goongerah is a community on the Brodribb River, located in Gippsland, Australia, near Mount Ellery.  The town's population is about sixty. The Snowy River is a major river in south-eastern Australia.  It originates on the slopes of Mount Kosciuszko, Australia's highest mainland peak, draining the eastern slopes of the Snowy Mountains in New South Wales, before flowing through the Alpine National Park and the Snowy River National Park in Victoria and emptying into Bass Strait.
