Hello Nat,
I think that Qld has always been at the lower price range. I guess the service fees will influence prices as it makes sense the sale average for $2,000 stallions is likely to be less than $6,000 so this is a factor. How many buyers travel to Sydney or Melbourne sales from Brisbane, compared to Sydney or Melbourne people travelling to brisbane to buy. The smaller number of buyers at the sale means less competition. With Rocklea track closed, Gold Coast closing due to the hospital, and the uncertainty over Albion Park and trainers looking interstate is it any wonder things were very bad.
I have been told by ( Very respected people in the industry )that I would get better prices interstate, so this is something that I will be looking at in future.
