Though I suspect this won’t be surprising, to give a sense of what’s going on in Australia, or NSW (the most populated state, about 1/3 people live there - and bc I just saw the release of data):

Names that significantly jumped up: [name_u]Remy[/name_u] and [name_u]Remi[/name_u] (boy and girl), [name_f]Hallie[/name_f], [name_f]Gabriella[/name_f] and [name_m]Muhammad[/name_m]. [name_m]Joshua[/name_m] one that has dramatically dropped.
Compare to the most used names given to Australian babies over the past 100 years:
Boys: [name_u]Michael[/name_u], [name_u]David[/name_u], [name_m]Peter[/name_m], [name_u]John[/name_u], [name_m]Matthew[/name_m], [name_u]James[/name_u], [name_u]Robert[/name_u], [name_u]Daniel[/name_u], [name_m]Andrew[/name_m], and [name_m]Christopher[/name_m].
Girls: [name_f]Jessica[/name_f], [name_f]Sarah[/name_f], [name_f]Jennifer[/name_f], [name_f]Michelle[/name_f], [name_f]Rebecca[/name_f], [name_f]Emily[/name_f], [name_f]Susan[/name_f], [name_f]Elizabeth[/name_f], [name_f]Emma[/name_f], and [name_f]Karen[/name_f].
I would have vaguely assumed the granny / vintage names would have eclipsed these names by now but I guess not - also because many not counted in this (ie Victorian names). This data set from 1930 on.
