Hi Jeff,
I cannot recall gate-to gate-values, I'm not even sure these were given.
However read the following snippet that I had on my austpac weather list archive - could always e-mail Harald and see if he has saved any data he obtained:

I played with the radar at Sydney office at the time. What made life
harder in this situation was the supercell south of the Ryde storm,
attenuating
the signal from the Kurnell Doppler radar. Around the time of the Ryde
tornado
(4:10 - 4:15 LT ??) a strong (yes, strong) mesocyclone was associated with
that
southern cell ~15 km W of the Sydney Metro area. I am about certain that
this meso
should have had a ground circulation as well, but I haven't heard a tornado
report from the S cell yet.
Here is a thought. The situation on 2 Feb 05 was potent enough
to consider some rather special warnings. If you would see a warning
issued that reads "Tornado Warning for Sydney Metropolitan", how do
you think that would be received?
BTW, if you'd like to make it into the NSW Spotter Hall of Fame (yet to be
build)
you could try and report a tornado in real time. I know from experience
that as
a chaser you are doing rather well if you manage to get half-decent video of
a tornado given
the adrenaline problems, but a real-time call to give a spotter report could
have
a huge positive impact on the warning services. An accurate spotter +
Doppler radar
package is a powerful warning "tool."
