I rarely see 'frontier' Mynas when I'm on back roads so it may be a
combination of suitable environmental corridors and food supplies. I have
seen Mynas picking at dead birds in the suburbs but not road kill in the
highway sense, so roadkill may not be a factor.
Some Victorian road reserves, particularly in Gippsland, aren't park-like
and could stop or slow down Myna colonisation - no Mynas in Mallacoota,
yet!

I know an ex truckie who travelled the Hume between Melbourne and the
border for many years, and he says he watched their gradual progress up
the highway.
I don't know if the rubbish dumped on the road reserves provided the
food to allow this, or whether the road reserves simply acted as a
disturbed environment needed to reduce competition from native birds.
Or it might be simply that the highways were a convenient place to
observe their spread, which may actually have been happening between the
roads too.
I guess access to road kill might be a factor. Do they eat dead birds
and animals?
