Sydney is an absolute monster too geographically - especially Western Sydney.
If you went as far North from Melbourne as you did West as that Penrith region is you're in regional Victoria, it's not 'Melbourne' - you're talking Gisborne.
The first time I went to Sydney I booked a hotel in Rooty Hill expecting it to be within 'Sydney', technically it is but it was a $113 one way drunken Uber ride from Circular Quay
That RSL is like the Crown Casino of pokies - like an old fogies arcade
