Taiwan's representative urges closer intelligence sharing and co-operation following concerns about China's intention in sending warships near Australia.
It had learnt first-hand China's intentions and capabilities from years of provocative incursions and Taipei was willing to collaborate with like-minded countries that wanted to protect the status quo, Douglas Hsu said.
Taiwan had a database of Chinese military actions and could share intelligence including the intention of some exercises and the messages they're designed to send out, Mr Hsu said.
"They're doing military drills in the region without pre-notice, I think that's not the right way to do that," he told AAP.
"My point is we need to learn from those lessons, China always wants to make a new bargaining chip by creating a new normal."
The ship was likely gathering intelligence but China also employed grey-zone tactics to push the boundaries and rewrite international rules, he said.
He pointed to creeping incursions by Chinese forces during military drills over the "median line" between China and Taiwan in the Taiwan Strait.
"The action has repeatedly proven that China is the destabiliser of regional peace and stability," he said.
Australia's voice in the international community was "definitely important" when it comes to calling out provocations, the envoy said.
Mr Hsu also urges closer ties with Australia, on Friday launching a Taiwan-Australia Relations Forum established by the Taiwanese community in Brisbane.
This includes trade as he pushed for Australia to help Taiwan join a trans-Pacific free trade agreement.
"Taiwan boasts a comprehensive and reliable technology supply chain, making it one of the most qualified applicants," he said.
China believes Taiwan is part of its jurisdiction, and rejects any application from Taipei to enter the trade agreement - which is a pact that China itself wishes to join.
Australia's policy includes a one-China principle, meaning it does not recognise Taiwan as a nation, but Australia only notes Beijing's claim over Taiwan and nothing more.
Tensions have resurfaced between Canberra and Beijing after a dramatic improvement in the relationship, with the government launching numerous protests against what it calls unsafe military actions that include a Chinese aircraft dropping flares dangerously close to an Australian helicopter.
Most recently, Australian officials protested with Beijing over a lack of notice about live-fire drills that interrupted dozens of commercial flights as three warships travelled down the east coast and around Tasmania.
Prime Minister Anthony Albanese acknowledged it was within international law but the government has made it clear more notice should have been given.
"We believe it was appropriate to have been given more notice and we made that clear last Friday," he told reporters on Friday.
The Defence Department says it's "best practice" to give between 12 and 48 hours' notice when opening a live-firing window, depending on the operation, and this includes what's known as an all-airmen broadcast.
But China's ambassador to Australia, Xiao Qian, rejects the claim that not enough notice was given.
A Virgin pilot was the first to report the drill after hearing the emergency broadcast mid-flight some 30 minutes following the live-firing window opening.
The warning was relayed to civil aviation authorities who reported it to the defence department.
Different countries had different practices depending on the nature of drills, Mr Xiao told ABC News, saying the Chinese alert was appropriate.
"I don't see there's any reason why the Chinese side should feel sorry about that or even ... apologise for that," he said.
The ambassador also played down concerns about the location of the naval task force, saying as a major power, Chinese vessels were present in the region and training was normal for navies across the world.
"There should be no over-reading into this."
Australia and allies regularly conduct freedom of navigation exercises in the Taiwan Strait, which Beijing sees as provocative.
