Anthony Seibold resurfaces as PNG Chiefs assistant after Manly sacking

The short answer

Anthony Seibold is an NRL coach who was sacked as head coach of the Manly Sea Eagles in March 2026 after just three games, following a series of losses. On July 31, 2026, the PNG Chiefs – an expansion team entering the NRL in 2028 – announced he had signed as an assistant coach under head coach Willie Peters. Seibold had been spotted touring the club's Port Moresby facilities the previous week. The Chiefs are assembling a star-studded roster, including Jarome Luai, Alex Johnston and Zac Lomax, and see Seibold's head-coaching experience as an asset. Seibold previously worked with Peters at South Sydney (and, per Fox Sports, also at Newcastle), and with fellow assistant Luke Burt at South Sydney. He said in a club statement he was excited to support the club's vision and make a positive impact in Papua New Guinea. The club's general manager of football, Michael Chammas, said Seibold would be a trusted advisor to Peters. Seibold is expected to join the Chiefs in November 2027, ahead of their inaugural season. Before this role, he had been working part-time with AFL club Collingwood after his Manly exit.

Why it's trending

The trigger for sudden interest is the official confirmation on July 31, 2026, that Anthony Seibold had been hired as an assistant coach by the PNG Chiefs. The news came days after the club announced the signing of Zac Lomax and following reports that Seibold had been seen in Port Moresby touring facilities. Seibold's high-profile sacking from Manly and his quick return to an NRL coaching role made it a notable story for rugby league fans.

Anthony Seibold, the former Manly Sea Eagles head coach who was sacked in March after just three games, has landed a coaching lifeline with the PNG Chiefs. The expansion club confirmed on July 31, 2026, that Seibold will join as an assistant coach under head coach Willie Peters, according to Nine.com.au, Fox Sports and The Canberra Times. Seibold was spotted travelling to Port Moresby last week to tour the club's facilities, Nine reported, and is expected to formally join the club in November 2027.

Multiple sources corroborate the core details but offer slightly different accounts of Seibold's history with Peters. Nine.com.au says Seibold, Peters and Luke Burt 'all done a stint together at South Sydney,' while Fox Sports reports that Seibold and Peters worked together at both Newcastle and South Sydney. Fox also notes that Seibold had been working part-time with AFL club Collingwood since his Manly exit – a detail absent from Nine's report. The Canberra Times adds that Seibold is a former Dally M Coach of the Year, underscoring the pedigree he brings to the expansion side.

The timeline begins with Seibold's dismissal from Manly in March 2026, after the team lost its first three games under him. He was replaced, though the sources do not detail the replacement. In the months that followed, Seibold took a part-time role at Collingwood. Then, in the last week of July 2026, he was seen in Port Moresby, fuelling speculation. On July 31, the Chiefs made it official, announcing him as an assistant coach. The Chiefs have been busy, having announced Zac Lomax's signing days earlier, joining Jarome Luai and Alex Johnston on the roster for their 2028 NRL entry.

For the PNG Chiefs, Seibold's appointment adds significant experience to a coaching staff that includes head coach Willie Peters and fellow assistant Luke Burt, who has coached Queensland Cup side Burleigh since 2023, per Fox Sports. Chiefs football general manager Michael Chammas said Seibold's head-coaching background will make him 'a trusted advisor to Willie.' Seibold's familiarity with the club's coaching staff is expected to ease the transition as the team builds toward 2028. Watch for further roster and staff announcements from the Chiefs as they continue assembling their foundation, and whether Seibold's role expands as the club grows.
