Conversely, Google Maps is lame for transit everywhere in the world, whereas at least Apple Maps is making rapid progress here.
I visited a dozen+ countries in 4 continents last year - GMaps did a pretty decent (often great) job with public transit. In the cases where there was no/bad data, it usually had more to do with the transit authorities being jackasses than anything in Google's control (Melbourne in particular stuck out as being just terrible).
BTW, the Android-App "Öffi" has full support for Melbourne, as Melbourne provides a simple to use API, and has for the past years.
