For Queensland:
2028: Callide B
2035: Gladstone
2036: Tarong and Tarong North
2042: Kogan Creek
2044: Stanwell
2050: Callide C
2051: Milmerran

It's very likely the some of these will shut down, either some or all units within a power station, early. Particularly the Central Queensland power stations where a lot of the constraints lie.
