Invasive species have major economic and environmental impacts in Australia and are a major cause of extinctions worldwide. Monitoring is crucial for the timely control of invasive species in sensitive environments. Early detection increases the probability of eradication and increased accuracy in detection reduces the impact of control programs on non-target species. Efficient monitoring also is crucial in determining whether eradication has succeeded. Search Theory has been applied for over 60 years in a wide range of non-biological monitoring problems, resulting in large increases in target detection rates. Gains of a similar magnitude in invasive species detection would greatly enhance Australia's capacity to manage these threats.

入侵物种对澳大利亚的经济和环境产生重大影响，是全球范围内的主要原因。监测对于及时控制敏感环境中的入侵物种至关重要。早期发现可增加根除的可能性，提高检测的准确性可减少控制方案对非目标物种的影响。有效的监测对于确定根除是否成功也至关重要。搜索理论已经在广泛的非生物监测问题中应用了60多年，导致目标检测率大幅提高。如果在入侵物种检测方面取得类似的进展，将大大提高澳大利亚管理这些威胁的能力。
