Dysart & Bendigo aren't "double-line manual track block sections",
they are the end of a double line block section.  The only Track
Block sections in Victoria are between Nth Geelong A  - Nth
Geelong B - Geelong A, and Sunshine - Brooklyn - Newport (West
Line).  Big difference.

Back to Dysart.  It is, according to SW.093/2000, a Non-Terminal
station, so the line has to be clear and the points set correctly
for 400m past the Home Signal before line clear can be accepted.
This would therefore mean that after you had accepted line clear
for a Down train to approach Dysart, you couldn't theoreticaly
dispatch an Up.  I don't think this happens in practice.  This is
actually a bit silly, as if the points are set for an up move, the
sequence of signals before fouling the up line would be Repeater
at Warning, Auto at Stop, then a Home at Stop.  Lots of overlap.

Now to Golden Square.  This is shown as a Terminal Station during
clear weather.  So you can accept a down train as long as the line
is clear as far as the Home signal, not 400m beyond.

Does the Victorian rulebook still make provision for "line clear
but station or junction blocked" anymore?

Nope.  ABS from NPT, WIL remote controlled by NPT.
