The Commonwealth of Murrumbidgee is a titanic, efficient nation, remarkable for its compulsory military service and complete absence of social welfare. The hard-nosed, hard-working, devout population of 24.137 billion Murrumbidgeeans are free to succeed or fail in life on their own merits; the successful tend to enjoy an opulent (but moralistic) lifestyle, while the failures can be seen crowding out most jails.

The medium-sized, moralistic, pro-business government prioritizes Spirituality, although Law & Order, Industry, and Defense are also considered important, while Welfare receives no funds. Citizens pay a flat income tax of 18.1%.

The powerhouse Murrumbidgeean economy, worth a remarkable 1,045 trillion dollars a year, is quite specialized and led by the Pizza Delivery industry, with major contributions from Book Publishing, Trout Farming, and Information Technology. Average income is 43,323 dollars, but there is a significant disparity between incomes, with the richest 10% of citizens earning 148,633 per year while the poor average 9,268, a ratio of 16.0 to 1.

Murrumbidgee has designated Murrumbidgee City as its capital city, abortion is only legal in unusual circumstances, Leader has just been declared ruler of Murrumbidgee in an international press conference, and a major religion has been named as Murrumbidgee's national religion. Crime is a problem, possibly because it is difficult to make it through a day without breaking one of the country's many regulations. Murrumbidgee's national animal is the kangaroo.

Murrumbidgee is ranked 13,644^th in the world and 7^th in Australia for Largest Populations, with 24.1 billion capita.
