I can't see a way to access that without using private C++ API.

The actual font size seems to be stored in QQuickTextPrivate::layout. You can see this if you add the following debug statement to qquicktext.cpp:

diff --git a/src/quick/items/qquicktext.cpp b/src/quick/items/qquicktext.cpp
index be86b29..2a7db4e 100644
--- a/src/quick/items/qquicktext.cpp
+++ b/src/quick/items/qquicktext.cpp
@@ -1098,6 +1098,8 @@ QRectF QQuickTextPrivate::setupTextLayout(qreal *const baseline)
     if (truncated != wasTruncated)
         emit q->truncatedChanged();
 
+    qDebug() << layout.font() << font;
+
     return br;
 }

Also, use this modified version of your example:

import QtQuick 2.0

Rectangle {
    width: 200
    height: 200

    Text {
        id: st
        anchors.fill: parent
        fontSizeMode: Text.Fit
        minimumPointSize: 6
        font.pointSize: 120
        text: "Size me if you can!"

        Rectangle {
            anchors.fill: parent
            color: "transparent"
            border.color: "darkorange"
        }
    }
}

As you resize the window, you see something like:

QFont( "Ubuntu,18,-1,5,50,0,0,0,0,0" ) QFont( "Ubuntu,120,-1,5,50,0,0,0,0,0" )
QFont( "Ubuntu,19,-1,5,50,0,0,0,0,0" ) QFont( "Ubuntu,120,-1,5,50,0,0,0,0,0" )
QFont( "Ubuntu,20,-1,5,50,0,0,0,0,0" ) QFont( "Ubuntu,120,-1,5,50,0,0,0,0,0" )

Why do you need to know the size of the text?
