Great Tasman Range

The Great Tasman Range is a 1000km long mountain range along the East coast of New Duveland. It starts from Seatown, Mirani and reaches Esperance, Lapérouse. The Highest peek, Mount Abel, reaches 4,125 metres above sea level, snowfall is uncommon in the area outside of winter. The range is New Duveland's most substantial mountain range, being one of the longest in the Pacific region outside of Australia. The extreme change in landscape across the eastern New Duvian coast affects weather patterns across the country, with the east side facing heavy rainfall, allowing short rivers to flow into the Tasman Sea. The Western side receives smaller amounts of rainfall, but larger river volumes, with the longest river being the Plymouth River, forming a small delta in which the city of Plymouth rises. The western areas are very fertile and flat with large volcanic plains stretching across the landscape. The Tallest mountain in the ranges in Mount Luiz, at 4,132m tall.

Snowfall is rare, but not uncommon in the southern region, several ski fields have been opened but all have failed due to a lack of constant snow, the only place on which it snows regularly is Cascade, Norfolk on Diemen Island, which is along the New Holland-Duveland border at an altitude of 2,016 metres.
