Hi Chrome,
I found this chart for Victorian class/weight ratings which may help .

Rather than type out the whole thing here is a link.

Hope it's not against forum rules. If you can't access it because of the rules I'll type it all out.

I think NSW racing has the equivalent class/weight ratings as Victoria.

For Qld,SA and WA subtract 3.0 kg from the Vic and NSW figures.

Tasmanian ratings are generally between 1.5 kg and 3.0 less than QLD,SA and WA.

NT ratings are generally 1.5 to 3.0 kg less than Tasmania

The Victorian chart is from one source and the adjustment by subtracting for different States is from another x-pert.

Also according to the x-pert races 18oom and over don't contain the same strength as shorter races and 2.0kg should be deducted from the relevant State class/weight rating. I'm presuming that he is not including G1,G2,G3 and Cox Plate Melbourne Cup etc
