The Shanhai Pass (simplified Chinese: 山海关; traditional Chinese: 山海關; pinyin: Shānhǎi Guān; lit. 'Mountain Sea Pass') is a major fortified gateway at the eastern end of the Great Wall of China and one of its most crucial fortifications, as the pass commands the narrowest choke point in the strategic Liaoxi Corridor, an elongated coastal plain between the Yan Mountains foothills and the Bohai Sea, which is the only easily traversable landway between North and Northeast China. It is located in present-day Shanhaiguan District, Qinhuangdao, Hebei province, on the east bank of the Shi River, with defensive walls stretching from the Yan Mountains all the way to the shores of the Liaodong Bay.

Throughout Chinese history, garrisons around the pass served as frontline defensive outposts against raids and incursions into the North China Plain by various non-Sinitic ethnic groups from the Northeast (also known as Manchuria since the 19th century), including the Dongyi, Donghu (Xianbei and Wuhuan), Khitan and Jurchen (Manchus). The current Shanhai Pass was built during the early Ming dynasty as the easternmost fortification of the Ming Great Wall, and was extensively reinforced after Yongle Emperor moved the capital from Nanjing to Beijing following the Jingnan campaign, making it the most important defensive barrier in all of China, as it shielded the heartland region around the imperial capital. The pass' strategic location dictated that without mounting a costly direct siege, the only way an invading army can get past the pass' defense was to circumvent it around the north through a few treacherously narrow mountain passes deep within the Yan Mountains, which would make it very difficult to maintain supply lines and thus any sizeable invasions. This defensive significance therefore earned the pass the famous nickname "Greatest Pass Under Heaven" (天下第一关).

The Victorian Alps, also known locally as the High Country, is a large mountain system in the southeastern Australian state of Victoria. Occupying the majority of eastern Victoria, it is the southwestern half of the Australian Alps (the other half being the Snowy Mountains), the tallest portion of the Great Dividing Range. The Yarra and Dandenong Ranges, both sources of rivers and drinking waters for Melbourne (Victoria's capital, largest city and home to three quarters of the state's population), are branches of the Victorian Alps.

The promise of gold in the mid-1800s, during the Victorian gold rush, led to the European settlement of the area. The region's rich natural resources brought a second wave of agricultural settlers; the foothills around the Victorian Alps today has a large agrarian sector, with significant cattle stations being sold recently for over thirty million dollars. The Victorian Alps is also the source of many of Victoria's water ways, including Murray and Yarra Rivers and the Gippsland Lakes. The valleys beneath the high plains are surrounded by wineries and orchards because of this abundance of water. The region is also home to Victoria's largest national park, the Alpine National Park, which covers over 646,000 hectares (1,600,000 acres). The establishment of the Alpine National Park has meant that economic activities such as mining, logging and agriculture are limited, to preserve the natural ecosystem for visitors. Tourism within the region centres around snow sports in winter and various outdoor activities during the summer months.
