For decades，the relationship between the Philippines and Australia has largely operated under the background of the US-centric Asia Regional Alliance spokes system. In general，the diplomatic activities between the two countries is centered on the US，and bilateral relations have developed steadily and gradually，making the Philippines-Australia bilateral relationship sufficiently independent. Although the Philippine-Australian bilateral relationship lacks a solid economic foundation，the Philippines and Australia are still expected to maintain the existing development trajectory of political，economic，and security relations.
