[b][u]Oceania[/u][/b]
[i]For the purposes of this guide, 'Oceania' includes any and all island nations in the Pacific Ocean other than those addressed in above sections, as well as Australia and New Zealand[/i]

[b]Australia[/b]
Australia was a key ally during the Cold War, and this remained the case after the Heavenfall. As the impact did little to affect Australia, the nation was instrumental in supplying relief and support to its' northern hemisphere allies in the wake of the disaster. 
As one of the major advanced and developed nations of the Southern Hemisphere, Australia took a leading position in the N/UN along with Brazil, and was one of the founding nations of the newly formed international alliance. 
Australia has welcomed and accommodated many displaced people to its' shores following the Heavenfall, resulting in many towns and cities expanding in size. The country has somewhat struggled to cope with this influx of people and initially there were struggles for emergency services and public utilities and the economy and other social systems to cope, but this has started to become less of an issue as more investment has been put into these areas. 
As part of its' new world-leading and facing role and increased importance to and in global affairs, Australia has also expanded its' armed forces, especially with reference to long-range naval and air assets and the ability to project power globally. The Royal Australian Navy recently bought its' first new aircraft carrier for decades into service, along with a fully capable air wing, and this has been a contentious presence in the region, due to concerns about the shifting balance of power. 

[b]New Zealand[/b]
New Zealand remained a strong ally throughout the Cold War and into the 21st century. When the Heavenfall struck, severe earthquakes and volcanic activity beset both North and South Islands of the country, and extensive rebuilding followed. 
In the wake of this, New Zealand emerged as a key member of the N/UN, though did not undergo the same expansion of its' population or armed forces like Australia, though some investment and development was made in these areas. Nonetheless, the countries' economy has expanded and it has welcomed a moderate intake of displaced persons. Industry has developed more into white-collar professions and services, though farming and agricultural exports still remain a high priority and major source of national income, along with tourism and the film and television industry. 

[b]Micronesia, Melanesia, and Polynesia[/b]
[i]Author's Note: the sheer number of island nations and individual islands in the Oceania region makes individual entries - especially distinct and non-reptitive ones - a massive task, so as such, they will be condensed into a single entry for the meantime that gives a broad overview of the state of the region as a whole.[/i]

The pacific island nations comprising the areas of Micronesia, Melanesia and Polynesia were savagely damaged by the tectonic and tidal activity of the Heavenfall. So many of them relied on maritime trade, industry and transport for their well-being, that the initial damage followed by the heavy flooding from rising global sea levels devastated many of these small, but historically and culturally rich places. Some islands were rendered uninhabitable, or even completely disappeared in the wake of earthquakes or volcanic activity. Others experienced tremendous hardships as they were forced to rebuild from ruins and ashes. 
Some were heavily invested in by megacorporations, while others allied with the N/UN, NCAA or other groups, forming a very patchwork region. As such, development on many of them has improved with modern roads, harbours and port facilities, airports and other such transport links, as well as new hi-tech industries and services, housing, education and medical facilities and other such modern utilities. 
Nonetheless, marine agriculture and other maritime occupations along with tourism remain key industries for the survival of these nations, and they still adhere to many of their key traditions and cultural identity. 
Most of them have no formal defence or military forces, and rely on their alliances and treaties for safety and security. 

[b]San Borondon[/b]
A large island nation in the Pacific, San Borondon is remote, sitting approximately three thousand miles away from Hawaii. Discovered by the Spanish in the late 1600s, the island was found to be rich in natural resources (namely gold). This and its tropical climate, well suited to a variety of cash crops, made it a target for the European empires. It switched hands from the Spanish to the French to the English, and briefly during World War 2, the Japanese. Throughough its three hundred year occupation, San  Borondon's native peoples fought an on-and-off guerrilla war against the various foreigners. 

San  Borondon was essentially in the middle of nowhere but occupied an important strategic space as a midpoint between the Americas and Asia. Thus, it spent the Cold War being courted by both sides.  
The country  dealt in a huge  amount of shipping as well as the sale of natural resources, but the wealth remained  with a few important families and their friends/investors. Most of the island lived in poverty, with those on the coast subsisting on fishing and those inland mining or farming, or working in the cities. The capital was essentially a larger Kowloon, millions of people packed into high-rise tenements and shanties. This was of course a breeding ground for crime, with foreign and domestic gangs seeking to control the smuggling on the island.

The reigning monarch has inherited a shaky political and cultural situation following the death of his father, and San Borondon remains in a state of flux between various cultural, political and ideological groups, all vying for control of the county. Currently unaligned to any international group or entity, the country is a hotspot in the South Pacific, important strategically for its' resources and location, but a difficult situation to approach and even more so to resolve quickly or easily.
