The megafauna extinctions were 10s of thousands of years ago and long
preceded dingos' arrival, which was only about 4,000 years ago, after the
Ice Ages ended and the seas rose.

Very true - we know that the "mega fauna" died out around that time (I guess
more likely because of human impact or climate change than dingoes?) and it
seems reasonable to assume that a lot of small stuff may have died out as
well - but I guess we lack the fossil records for them - or at least they
are not publicised?
