Apra Harbor in Guam sits along the Asia-Oceania trade corridor, handling coal, iron ore, LNG, agricultural products, and containerised manufactured goods. Australia's position as the world's largest exporter of iron ore makes its port infrastructure strategically significant for global commodity markets. Tropical cyclone season (November–April) is the primary natural hazard, particularly along Australia's northern and western coasts; the iron ore ports of Western Australia have historically caused global price spikes during cyclone-related closures. Australia's biosecurity and PSC regimes are among the strictest in the world — AMSA inspections under the Tokyo MOU framework focus on vessel safety, crew competency, and environmental compliance, and biosecurity holds for ballast water or hull fouling can cause significant delays.
Routed sea distances from Apra Harbor to the principal global hubs, computed by ArcNautical's routing engine — around land and through the canals a ship actually uses, not great-circle.
Guam is a multi-MoU jurisdiction (its port states participate in more than one regional PSC programme). Vessel-level detention probability for calls at Apra Harbor is computed by ArcNautical's scoring engine using flag performance, vessel age, deficiency history, and ownership opacity rather than a regional aggregate.
No port calls were observed at Apra Harbor between 29 Apr 2026 and 5 Aug 2026. This reflects the reach of the terrestrial AIS network behind this page — coverage is densest in Northwest Europe and thins elsewhere — and is not a statement about traffic at Apra Harbor. The feed has delivered no positions since 5 Aug 2026, so these figures will not change until it resumes.
