Weather and climate

Warm semi-tropical summers, particularly in lower central area. Mountain areas in the west are cooler, particularly in winter. Rainfall is heaviest from March to June.

The landscape ranges from the subtropical, rainforest clad regions of the north to the Snowy Mountains in the south, which contain Australia's highest point, Mt Kosciuszko (2,228m/7,310ft), prominent alongside glacial lakes and stunning valleys.

The southern coastline of New South Wales is home to 30 national parks, an abundance of bays, coves and dazzling beaches, especially around Jervis Bay and the Sapphire Coast. Contrasting that is the rugged outback territory found at Mungo and Mutawintji National Park, where previous settlements and old mining towns unearthed the mineral rich deposits of the area.

There are over 1,300km (800 miles) of coastline and four UNESCO World Heritage sites including Lord Howe Island, the Greater Blue Mountains area, Willandra Lakes and the Gondwana Rainforests.
