There was no illegal or suspicious activity to report as the Australian Navy ship HMAS Stuart and Nafanua III completed the surveillance of Samoa's Exclusive Economic Zone. 

The HMAS Stuart was back in Samoa on Wednesday after a decade.

Commanding Officer Commander Richard Raymond said no illegal activities were detected during the visit, but added that the Australian Defence Forces will continue to monitor the area to ensure the safety and security of both nations.

The HMAS Stuart vessel used its radars and sensors to detect other ships and flew a helicopter to detect any signs of illegal activity while in Samoa.

When transiting the Exclusive Economic Zones (EEZ) of Pacific Island Forum nations, such as Samoa, vessels like the HMAS Stuart monitor the area for illegal fishing or other illegal activities. 

"We observe them and compare them to what we understand to be normal and legal. And then if there's anything illegal, we report that back for action from the Samoan government," said Cmdr. Raymond.

The ANZAC-Class frigate was berthed at the Apia Wharf on Thursday and was open to the public and government officials for tours of the whole ship. The ship has a crew of 182.

Schools such as Vaiala Beach School were in attendance, as were children from the Samoa Victim Support Group, to explore the vessel inside and out. One parent helper added that this was a great experience and opportunity for the children. 

When asked about the relationship between Australia and Samoa, Cmdr. Raymond stated that the Australian Defence Forces are committed to supporting the Samoan Government in monitoring its borders and ensuring its security. 

He also mentioned that they have not received any requests from the Samoan Government to increase their activities in the region.

After Samoa, the HMAS Stuart will head back to Perth, Australia on Friday where they will rest for two months for maintenance.
