Coyle, currently chief of joint capabilities, will replace Lieutenant General Simon Stuart, the government said. Her appointment comes as the Australian Defence Force seeks to increase female representation and address allegations of systemic sexual harassment and discrimination.

Defence Minister Richard Marles described the move as a “deeply historic moment,” adding that Coyle’s leadership would be significant for women serving in the military and those considering enlistment.Coyle, 55, joined the army in 1987 and has held several senior command roles.

Marles said she would also become the first woman to lead any service branch within the ADF.Women currently account for about 21% of ADF personnel and 18.5% of senior leadership positions. The military has set a target of raising female participation to 25% by 2030.

The leadership changes come after a class action lawsuit filed in October alleged the ADF failed to protect thousands of female personnel from sexual assault, harassment and discrimination.

In parallel appointments, Vice Admiral Mark Hammond will become chief of the ADF, replacing Admiral David Johnston, while Rear Admiral Matthew Buckley will take over as head of the navy.

Thousands of troops are set to march in the capital Naypyidaw, where Min Aung Hlaing is expected to deliver a speech aimed at reinforcing morale within the armed forces, which have been engaged in a protracted civil conflict since the 2021 coup.

State media reported that “leadership changes” would follow the ceremony, quoting deputy commander-in-chief Soe Win as saying adjustments were imminent within the military hierarchy.

Under Myanmar’s constitution, Min Aung Hlaing would need to relinquish his military role to formally become president. He currently serves as acting president, and a permanent transition would coincide with a parliamentary process expected to begin next week.

Min Aung Hlaing has ruled since overthrowing the elected government of Aung San Suu Kyi in 2021, detaining the Nobel laureate, dissolving her party, and triggering a nationwide conflict involving pro-democracy forces and ethnic armed groups.

Recent elections, which handed pro-military parties a decisive victory, have been criticized by democracy monitors as tightly controlled and excluding opposition participation.

Despite ongoing violence, the military has regained some ground over the past year, aided in part by China-brokered ceasefires with key ethnic armed groups. Agreements involving regions such as Lashio and parts of Mandalay have helped the junta stabilize certain fronts after earlier setbacks.

However, fighting remains widespread in many areas, with analysts noting the conflict is highly fragmented. According to monitoring group ACLED, more than 90,000 people have been killed since the coup, while the United Nations estimates over 3.7 million have been displaced and roughly half the population lives in poverty.

The Armed Forces Day ceremony, once a large-scale display of strength, has diminished in scale in recent years as the military contends with battlefield losses and internal strain.

The assembly convened its first session a day earlier, where delegates are expected to deliberate amendments to the socialist constitution and formalise leadership positions, including the chairmanship of the State Affairs Commission. The body, widely regarded as a rubber-stamp legislature, typically meets after major party congresses to translate ruling party decisions into state law.

The session will also review the country’s economic five-year plan announced at the ninth Workers’ Party Congress held in February, according to KCNA.

Attention has centred on whether Pyongyang will amend its constitution to codify Kim Jong Un’s “two hostile states” doctrine toward South Korea. In recent years, the North Korean leadership has shifted away from its longstanding policy of peaceful reunification, formally redefining the South as an adversarial state.

Such a move would mark a significant institutional shift, embedding the current security posture into the country’s legal framework.

Kim Yo Jong, the leader’s sister and a key political figure, was absent from KCNA’s list of members of the State Affairs Commission, where she had served since 2021. South Korea’s Unification Ministry said it was examining the development.

Analysts said her omission did not necessarily indicate a reduction in influence. Lim Eul-chul, a professor at Kyungnam University, said the move could reflect a strategic redistribution of roles, with Kim Yo Jong continuing to exercise authority within the ruling Workers’ Party in a policy coordination capacity.The developments come as North Korea continues to consolidate internal governance structures while signalling a hardened stance on inter-Korean relations.
