How long has sustained economic growth persisted in Australia as of the provided data?

The correct answer, which states that sustained economic growth in Australia has lasted for 22 years, reflects a significant period during which Australia experienced continuous growth without experiencing a technical recession, defined as two consecutive quarters of negative economic growth. This period of growth began in the early 1990s and continued into the 21st century, making Australia one of the developed nations with the longest uninterrupted economic expansion.

This sustained growth can be attributed to various factors, including strong demand for Australia's natural resources, structural reforms in the economy, effective monetary policies, and consistent foreign investment. The resilience of the Australian economy, even during global economic downturns, allowed it to maintain positive growth rates relatively consistently.

While other options suggest different durations, none accurately reflects the recognized extent of economic growth in that given timeframe. The other choices either underestimate or overestimate the period of this growth, making 22 years the most accurate representation based on historical economic data.
