Recent years have accelerated the change in the perception of the international environment by the Australian government, where previous international trends have rapidly accelerated from the Australian perspective, which has forced changes in the current security strategy and has also influenced the international actions taken. The Indo‑ Pacific region is becoming a point of reference for Australia, and emerging new challenges and threats are forcing changes to the current policy. Thus, in recent years Australia has been modifying its strategic assessment and taking action to adapt to the situation and attempt to maintain the current, favorable „rules‑ based” international order. China and its policy have emerged as the main strategic challenge. Hence Australia is invigorating its involvement in multilateral institutions in the region together with new minilateral formats (Quad, Aukus) and bilateralism. However, China does not exhaust all contemporary challenges to Australia’s security, hence we are dealing with a change in the current vision of state defense and security strategy to an approach that is intended to engage not only state institutions, but the entire society (whole‑ of‑nation strategy).
