Every commonwealth country, but it's her Governors General that actually do the signing (Royal Assent) on her behalf. Local govt chooses who she will appoint though, and the GGs are (more than HM even) usually just a ceremonial thing and have never actually mattered much except for one time in the 70s when the GG just straight up removed Australia's Prime Minister (for the CIA, allegedly).
She also chooses some of the senior leadership of the Church of England because she's the head of that too, but really that's also a UK PM choice, but really since 2007 the church just chooses it.
